Avast For Mac Web Shield Blocking All Internet



I need help to find the cause and/or stop a virus message that keeps popping up in AVAST Mac Security application. It started several weeks ago and now pops up everytime i am on the internet. Sometimes it pops up ten times in a row with different URL that it is supposedly blocking. Combine all of this with an information that web is the most frequent attack vector these days, so might to argue that Web Shield is more important then a Filesystem Shield in these days.

In the Web Shield Settings go to item Site Blocking and enable the feature. If you have setup the list correctly, you should get the message “Avast Web Shield Warning. SITE BLOCKED”. These steps are also applicable for all Avast Antivirus solutions (i.e. Also for Avast Pro Antivirus, Avast Internet Security, or Avast Premier) running.

Core Shields are the main protection components in Avast Antivirus. The Core Shields are: File Shield, Behavior Shield, Web Shield, and Mail Shield. By default, all Core Shields are enabled to provide optimal protection. Avast Antivirus shields actively analyze suspicious information both sent from and received to your PC, as well as potentially malicious content stored within your PC. These components detect and block malicious files, dangerous websites, unauthorized connections, and other threats.

Enable or Disable all Core Shields

Core Shields are your PC's main defense against malware. All shields are enabled by default for your protection, but all the shields can be instantly disabled for troubleshooting purposes. To disable all Core Shields temporarily:

  1. Open the Avast user interface and go to MenuSettings.
  2. Select ProtectionCore Shields.
  3. Click the slider so that it turns to red (OFF), and select the duration of time Core Shields will be disabled.

All Core Shields are now temporarily disabled. To enable all Core Shields, follow steps 1-2 above, then click the red slider so that it changes to green (ON).

Configure Core Shields sensitivity

In this section of the Core Shields settings, you can determine the sensitivity of the shields. The higher the sensitivity, the higher the protection and potential for false positive malware detections. Reducing the sensitivity reduces the chance of false positive detections, but may also reduce the effectiveness of the Core Shields. Sensitivity is set to Medium sensitivity by default, but can also be set to High sensitivity or Low sensitivity. To change your Core Shields sensitivity:

  • Click and hold the white marker, then slide it to your desired sensitivity setting.

Configure Core Shields behavior

In this section of the Core Shields settings, select the tab for Virus or Potentially unwanted programs (PUPs), and define the actions to be performed when each type of virus is found on your PC. Configure the following behavior settings:

  1. Actions: select which action Avast applies when a Viruses and Potentially unwanted programs (PUPs) are detected. We recommend selecting Fix automatically.
  2. Enable CyberCapture Technology: define how you want to treat a threat on your PC. You can select Always block a threat to allow Avast to block the threat automatically, or Ask me about decision to receive a notification every time a threat is detected on your PC.
  3. Enable Hardened Mode: uses information based on reputation services to determine which executable files are safe to open.
  4. Enable Rootkit detection: enables Avast to monitor hidden malicious threats in the system. Unticking this option may resolve potential compatibility issues that can cause system crashes.
  5. Enable Exploit detection: enables Avast to detect and block attempts to run malicious threats or processes in the memory from exploiting vulnerable applications on your PC. Unticking this option may result in potential compatibility issues that can cause system crashes.

Editor's Choice

Kaspersky Free Antivirus

Kaspersky Free Antivirus delivers excellent protection with a moderate performance impact, but it has few extra features.

Bitdefender Antivirus Free Edition

Bitdefender Antivirus Free Edition continues to be the best set-it-and-forget option among free antivirus products.

Avast Free Antivirus

Avast Free Antivirus offers lots of extra features, but its malware protection is mediocre and it may collect your browsing history.

Windows users need a strong antivirus program to ward off malware attacks, to keep their computers running efficiently and to safeguard their online identities and personal information. The best paid antivirus suites have many features to protect children, manage mobile devices and monitor a computer's firewall, software updates and other features. But some users don't want, or can't afford, to pay for those extra features and may need to go with a free antivirus program.

If that describes you, you've come to the right place. We've evaluated the best free antivirus programs based on their malware protection, system impact, ease of use and useful extra features. If you're undecided, check out our free vs paid antivirus comparison first.

So which free PC antivirus product would be best for you? Of the seven free antivirus programs we've recently reviewed, Kaspersky Free Antivirus barely edged out Bitdefender Antivirus Free Edition for the top spot. Both offer excellent protection against malware without slowing down your system, but Kaspersky lets you schedule scans and has a quick-scan option.

Bitdefender, however, is still the best 'set it and forget it' free antivirus option. After installation, it takes care of itself and doesn’t need user intervention. If you need to put antivirus software on your grandparents' PC but don't have time to maintain it, this might be the perfect solution.

Both Kaspersky's and Bitdefender's products offer only the basics. If you want features such as a password manager or a hardened web browser, normally found in midpriced paid antivirus suites, then Avast Free Antivirus might be for you. But its malware protection isn't as good as the top two and its performance impact is heavier.

Latest Security Alerts and Threats

— A new browser exploit kit targeting Windows uses 30 different languages infects legitimate websites and tries to get visitors to install fake Adobe Flash, Google Chrome or font updates. When run, the 'installer' actually installs a remote-access tool. ADVICE: Use robust antivirus software and don't trust pop-up windows telling you to update Flash, Chrome or fonts.

— Apple patched a security hole that let you -- or a malicious website -- jailbreak an iPhone and install any kind of app, including potential malware. (This is not among the flaws that let several websites infect any iPhone.) ADVICE: Make sure your iPhone, iPad or iPod Touch is updated to iOS 12.4.1.

— Diagnostic software loaded onto most Lenovo Windows computers made between 2011 and 2018 could be used to hijack a PC. ADVICE: Uninstall Lenovo Solutions Center from your Lenovo PC., and run Windows antivirus software.

Lean and mean

Kaspersky Free Antivirus

Reasons to Buy
Moderate performance hit
Reasons to Avoid

Kaspersky Lab doesn't advertise that it has a free antivirus product, and doesn't make it easy to find the download page. Too bad, because this is one of the best free antivirus products we've ever tested, with a no-nonsense but comprehensible interface, a light-to-moderate system-performance impact and Kaspersky's unbeatable malware protection. The only reason we're not giving Kaspersky Free Antivirus a 4.5/5 rating is because it offers no extra features.

No muss, no fuss

Bitdefender Antivirus Free Edition

Reasons to Buy
Super-easy to use
Reasons to Avoid
No quick scans or scan scheduling
Bitdefender Antivirus Free Edition

Like Kaspersky, Bitdefender Antivirus Free Edition offers nothing but the basics, and its malware protection is just as good, if a bit more prone to false-positive malware detections. Its scans are lighter on the system than Kaspersky's, but it offers fewer options — you can't even schedule a scan. It's best for users who want a set-it-and-forget-it security solution for themselves, or for a loved one.

Nearly a free suite

Avast download for mac

Avast Free Antivirus

Reasons to Buy
Highly customizable
Reasons to Avoid
Heavy performance hit

The malware protection in Avast Free Antivirus is a peg down from the top, but it's got the best assortment of extra goodies for a free antivirus program, including a password manager, a hardened browser and a network scanner. The program is also very customizable and offers limited access to Avast's VPN service. However, it caused a pretty heavy system load in our testing.

Finally good enough

Microsoft Windows Defender

Reasons to Buy
Built into Windows
Reasons to Avoid

Microsoft's built-in antivirus software has finally reached the big leagues. Windows Defender won't beat Bitdefender or Kaspersky in malware protection, but it holds its own against other free antivirus products while delivering a small system-performance impact and a surprising number of extra features, including parental controls and protection for all browsers. For the first time, we can recommend using Windows Defender as your primary antivirus solution.

Not enough oomph

AVG AntiVirus Free

Reasons to Buy
File shredder
Reasons to Avoid
Few extra features

AVG shares Avast's decent if unspectacular malware-detection engine while having a much lighter system-performance impact. But AVG AntiVirus Free has far fewer useful extra features than Avast Free Antivirus. The good news is that AVG's wide range of customization options and its file shredder are still available; the bad news is that there's no compelling reason to pick AVG over Windows Defender.

Not what it once was

Avira Free Antivirus

Reasons to Buy
Lots of add-ons
Reasons to Avoid
Most extra features are trialware

Avira Free Antivirus was the best free antivirus option just a few years ago, before Bitdefender and Kaspersky jumped into the ring and Avast, AVG and Windows Defender raised their game. Now Avira's malware protection is in the middle of the pack. Its numerous extra features are mostly just teases for paid services, and its system-performance impact is remarkably heavy. We do like that it's still got a wide range of customization options.

Has its ups and downs

Panda Free Antivirus

Avast Download For Mac

Reasons to Buy
Moderate performance impact
Reasons to Avoid
No opting out of data collection
Panda Free Antivirus

Panda doesn't take part in every lab test whose results we use, so its malware protection is a bit of an enigma. We liked Panda Free Antivirus' high degree of customization options and its appealing interface. We didn't like the constant ads for other Panda products, the attempts to hijack your web browser, and the fact that unlike every other antivirus company, Panda won't let you opt out of automatic system-data collection.

Honorable Mention

Essential side piece

Malwarebytes Anti-Malware Free

Reasons to Buy
Removes adware, other unwanted software
Reasons to Avoid
Manual definition updates
Malwarebytes Free Edition

Malwarebytes Anti-Malware Free is not antivirus software. It's more of a malware-removal tool. Malwarebytes Anti-Malware Free can't protect a PC from infection, but it does an excellent job of cleaning out malware that's already on your system. Plus, it doesn't interfere with any antivirus software that's already installed. We recommend Malwarebytes Anti-Malware Free as a complement to any antivirus program.

How We Tested

To evaluate installation, ease of use, interface and performance impact, we installed each AV program on the same Asus X555LA laptop, which ran Windows 10 and featured an Intel Core i3-4005U processor, 6GB of RAM and 36GB of data on a 500GB hard drive.

We conducted our own tests on how much each antivirus product affected our laptop's performance, using our custom OpenOffice benchmark. We timed how long it took to run a quick scan and a full scan while the laptop crunched numbers in the background.

We also assessed how easy each program was to use, the number of useful extra features it offered (including free add-on software) and how insistently each program nagged us to upgrade to paid software.

Our malware-detection data comes from four evaluation labs: AV-TEST in Germany, AV-Comparatives in Austria, SE Labs in England and our own lab in Utah. Each lab regularly tests major antivirus products for their abilities to detect zero-day malware and other threats.

While it's unlikely you'll ever run into malware for the Mac, you may want to consider an antivirus tool anyway—if not to protect yourself, but to protect your Windows-using friends from any malware you may inadvertently send their way. We think that Sophos Anti-Virus for Mac is the best choice, and it's free.

Update: Our previous recommendation for Mac Antivirus was 'nothing.' We know many of you choose to use nothing, but we also know you don't come to the App Directory to not get any suggestions at all. Besides, malware is starting to become a bit more prevalent on the Mac, and even the safest browsing habits don't protect you completely. So, we now officially recommend Sophos as our Mac antivirus of choice.

Sophos Anti-Virus for Mac

Platform: OS X (10.4+)
Price: Free
Download Page

Features

  • Compact, easy-to-use interface that can be used for custom on-demand scans of files, folders, and drives, or scheduled, periodic full scans of your Mac.
  • Also scans files on your Mac for known Windows malware, trojans, and viruses, and deletes or quarantines them so you don't risk spreading them to someone else via network share, USB drive, or email.
  • Deletes or quarantines known threats, gives you the option to quarantine anything suspicious that may be a new threat or dangerous file.
  • Runs quietly in the background, scanning emails, downloads, and any other files on access, stopping you from opening them before they can do any harm.
  • Light on system resources while running in the background.
  • Installs like any other Mac application, and uninstalls just as easily—no complicated packages or components to manage or configure.
  • Sophos' 'Live Antivirus' feature updates your app the moment new threats are detected or found in the wild. The feature also performs real-time lookups to see if files accessed are in the SophosLabs database, even if they're unfamiliar to the app.
  • Supports OS X up to 10.8 and back to 10.4, and is completely free for all versions.

Where It Excels

Sophos actually has an excellent breakdown of the history of malware for the Mac going all the way back to 1982. The fact that the article exists should remind Mac users that while they're not the primary target for malware authors, they're by no means invulnerable. The size of the article however should issue some confidence that the risk—while present—is by no means critical.

Sophos Anti-Virus for Mac stands out in a somewhat crowded field of Mac antivirus apps because it doesn't just scan your Mac's files and folders on demand, but it does it quietly in the background without tapping your already precious system resources in the process. The utility also keeps its own constantly-updating database of Windows viruses, trojans, and other threats, so if you inadvertently download a Windows virus or trojan that won't harm you, you don't run the risk of sending it off to someone else by forwarding the message, or you won't infect other computers on your network (or any Windows partitions or virtual machines you run on the same hardware) via shared drives. Sophos is smart enough to tell you 'Hey, this won't hurt you, but we're going to quarantine/delete it so you don't accidentally email this attachment to someone else.' That's a huge benefit—and it keeps you from being that guy no one likes.

Another banner feature Sophos offers that its competition doesn't is its live, real-time access to SophosLabs. 'Live Antivirus,' as it's called in the app, gives you an added layer of protection. The app automatically identifies and quarantines suspicious files, installers, and other packages that may not be well known threats yet, but definitely exhibit behavior suspicious enough that Sophos is looking into them.

Avast For Mac Reddit 50/50

Best of all though, in our testing, Sophos was one of the most resource-light antivirus apps on the Mac, which is impressive considering the features it offers.

Where It Falls Short

Sophos Anti-Virus for Mac isn't perfect, however. Even though it's pretty resource light, it wasn't the lightest in our tests. It just hit the sweet spot between resources and features. Also, support for Mountain Lion came a few months after its launch, so Sophos wasn't exactly right there with those people who upgraded on launch day.

The Competition

ClamXav 2 uses the open source ClamAV virus scanning engine. It can also detect both WIndows and OS X malware, scan on demand or on a regular schedule, and it's probably a bit more lightweight and easy on system resources than Sophos. It's compatible with OS X 10.5 or higher. The only trouble with ClamXav is that its definitions come a bit more sporadically than we'd like (daily, usually, sometimes, if they feel like it) and while performing scans is easy, tweaking all of the settings and getting the app scanning proactively is a little more effort than I'd like to see. Still, it's an excellent alternative, and one of the first you should check out if Sophos isn't cutting it for you.

Avast! Free Antivirus for Mac is the Mac version of our current favorite for Windows, and for good reason. The researchers at AV Comparitives found that Avast detected 100% of the Mac malware that went through it, an honor that few other utilities won (they didn't test Sophos, unfortunately). It's free, it works, it's lightweight, but the only catch is that it only scans for Mac-specific malware, which won't matter to you if you're in an all-Mac ecosystem, but if you, like most of us, share the world with Windows users, thinking of them doesn't hurt.

Avira is another free utility worth a look. It also picked up 100% of the Mac malware that passed through it with no false positives. Avira's UI and options are perfect for non-technical users, and it offers strong protection against known Mac threats. Again, there's no Windows protection in the app, and both the scheduling and custom scan options are a bit anemic, so power users may want to shy away from it. If you're installing it on your non-technical friend or family-member's Mac however, it's a great option.

Whatever you do though, it's probably not necessary to plop down money for a Mac antivirus suite. The threats don't warrant you dropping money on software to keep you safe, and too many of them do more harm than good (especially the ones looking to get your money). They're just not worth it, especially when there are more effective, robust, free options like the ones above available to you.

Avast For Mac Maverick

  3. Avast Mac Security Free
  4. Avast For Mac Maverick

The best free antivirus for Mac Avast Security for Mac Avast Security for Mac is one of the most popular security suites available, and it’s easy to see why. Avast Mac Security is one of the best free antivirus for MAC which helps you keep your MAC secure. It offers MAC virus protection at par with the paid ones. It can be used to scan MAC for virus. You can do the full system scan, removable volumes scan, custom scan, and scan for network mounted volumes.

Editor Rating: Good (3.0)
  • Pros

    Certified by one independent testing lab. Free. Speedy full scan. Network security scanner. Password manager. Website rating. Active Do Not Track.
  • Cons

    Poor scores in phishing protection test. Password manager includes only basic features. SiteCorrect feature did not work in testing.
  • Bottom Line

    Avast Security (for Mac) delivers effective malware protection along with unusual bonus features. It tanks our antiphishing test, but this free utility is still worth a look.

For years, Mac users basked in the mystique of virus-free computing. It wasn't true, alas, and as time goes on we see more and more Mac-specific malware attacks. The situation may not be nearly as bad as for Window or Android, but prudence still dictates that you install antivirus protection on your Macs as well. Avast Security offers Macs protection against malware along with advanced features including a password manager and a network security scanner, all for a cost of exactly nothing.

Installation went quickly, though I did find I had to separately activate the password manager and the Online Security browser extension from the Tools page. You'll also find Avast's SecureLine VPN on that page, but it's not free like the others. When you click to activate, you get a choice of signing up for $2.99 per month or starting a 30-day trial.

SEE ALSO: The Best Free Antivirus Protection for 2019

The product's spacious main window features a large status indicator centered in an otherwise-empty white region, with a menu down the left side. It's a very different appearance from Avast Free Antivirus on Windows, which uses pops of purple and green on a dark gray background.

Pricing and OS Support

Like Bitdefender and Kaspersky, Avast supports macOS versions back to 10.9 Mavericks. If you have an antique Mac that for some reason can't even run Mavericks, consider ESET Cyber Security (for Mac), ProtectWorks, or ClamXAV (for Mac) all of which support versions from 10.6 (Snow Leopard) on. At the other end of the spectrum, Avira, Trend Micro, and Symantec require macOS 10.11 (El Capitan) or better.

Free

Like Sophos and Avira, Avast offers full antivirus protection for free. Avast Security Pro (for Mac) costs $59.99 per year for one license or $69.99 for three. The Pro edition adds ransomware protection and real-time notification when new devices connect to your network. The free edition is strictly for non-commercial use; in a business setting, you must pay up.

Good Malware Protection Scores

When reviewing a Windows antivirus utility, I report how it scored with four independent antivirus testing labs. The very best products earn top scores from all four labs. But even if no test results exist, I can run my own hands-on tests using real-world malware and malware-hosting URLs.

It took years to develop my hands-on tools and tests for Windows. Most of them don't carry over to the macOS platform. Hence lab results become extremely important for my Mac antivirus reviews. Two of the labs I follow, AV-Test Institute and AV-Comparatives, test Mac antivirus, and Avast participates with one of them.

Experts at AV-Comparatives test Mac antivirus products using the latest macOS malware. They also evaluate each product's ability to detect Windows malware. Why? While a Trojan written for Windows wouldn't run on a Mac, the Mac could serve as a carrier.

Avast managed 99.9 percent protection against Mac malware. That's very good—better than most. However, Bitdefender and Kaspersky exhibited 100 percent protection. In the Windows malware test, Avast detected 100 percent of the samples. Most competing products also took 100 percent. However, Webroot only caught 75 percent, and Intego Mac Internet Security X9 got just 18 percent. Like most tested products, Avast received certification from AV-Comparatives for Mac antivirus protection.

Having one certification is good; having two is better. Bitdefender, Kaspersky, and Sophos are among the products that received certifications from both labs for Mac malware protection.

Scan Choices

Avast offers several scans to improve your Mac's security. A full scan on the Apple MacBook Air 13-Inch that I use for testing took 14.5 minutes, just a hair over Intego's 14 minutes, and quicker than the 18 minutes required by Avira. The average for recent products is 24 minutes, so Avast proved quite speedy. Norton is the current speed champ, completing a full scan in 10 minutes.

There's a separate scan for removable volumes, though you can configure the full scan to include them. I scanned a thumb drive containing my Windows malware collection and found that it quarantined 85 percent of them. For comparison, Avira detected 82 percent of these, while Sophos Home (for Mac) wiped out every single one.

There's no predefined quick scan, which makes sense given the speed of the full scan. The custom scan settings confused me, though. As with the full scan, you can add file locations to exclude from scanning, and configure it to scan Time Machine backups. But the full scan's settings include those options, and also let you include removable volumes and network volumes, while the custom scan's settings do not. Puzzling.

Avast Security Pro For Mac

You can schedule a daily, weekly, or monthly scan if desired. Settings for a scheduled scan include two additional choices. You can set it to skip scanning if your device is running on batteries, and you can have it wake from sleep if necessary, to perform its scheduled scan. Avira Free Antivirus for Mac not only offers scheduled scanning, it defaults to a weekly scan with no effort on your part. Sophos skips scheduled scanning, relying instead on real-time protection.

Network Security Scan

The final scan choice doesn't look for malware. Rather, it collects information about all the devices on your network and flags any security problems. On my own network, the scan finished in just under three minutes.

The scanner correctly reported that my main router has an open port that could theoretically become a point of attack. It's true that the port is open, as my ISP uses it to run remote diagnostics when necessary. But that function requires a key that only the ISP has.

More interestingly, it found serious problems with a network storage device (fortunately, one that I'm not currently using). Not only does this device have numerous open ports, it's vulnerable to a buffer overrun attack. Avast advised updating the firmware; I just unplugged it.

The report also serves as a list of everything that's connected to your network, identifying each by name and type. It's similar to the output of Bitdefender Home Scanner. With both products, I found devices with names like unknown6542990b6483—not much help! Bitdefender includes an option to edit the name and type, and it remembers your edits in subsequent scans. I'd like to see that ability in Avast.

Excellent Phishing Protection in Chrome and Firefox

In the Windows realm, one thing that differentiates Avast's premium product is better protection against phishing sites, those fraudulent sites that imitate secure sites and try to steal your login credentials. The free Windows edition scored very poorly, while the premium edition did an extremely good job. Based on initial round of testing, the Mac product's phishing protection, both free and Pro, seemed to match that of the free Windows product, meaning it's not very good.

I learned later that Avast's phishing protection is not fully functional in Safari. The developers are working on making it completely browser-independent. In the meantime, they advise using Chrome or Firefox. Norton was also having problems during my original test, so I tossed those results and started fresh.

My phishing protection test uses URLs reported as fraudulent, but not yet verified. Typically, these are only a few hours old. That's important, because phishing sites are ephemeral. Once they've been identified and blacklisted, the fraudsters just create new ones.

I simultaneously launch each URL in Safari on the Mac and in a browser protected by long-time antiphishing champ Symantec Norton Security Premium. I also launch each in Chrome, Firefox, and Internet Explorer, relying on the browser's built-in protection. If any of the five browsers throw an error message, I discard the URL. A true phishing fraud masquerades as a secure site and tries to capture your login credentials. Any URL that doesn't match that profile also gets junked.

I've written a Windows-based tool that handles launching URLs and capturing results. On the Mac, I copy and paste each URL into Safari and manually record the result. When I have enough data, I dump the five reports into Excel for comparison.

The malefactors that perpetrate these phishing frauds are clever. They're always devising new techniques to get past security software. That being the case, I report results not as hard figures but as the difference between the product under test and the others.

Tested using Safari's incomplete phishing protection, Avast's detection rate lagged Norton's by 32 percent, and Norton itself was having a bad day. All three browsers soundly drubbed Avast. When I retested using Chrome, Avast tied with Norton and beat the detection rates of the three browsers. That's impressive. Of the Mac security products I've tested, only Bitdefender did better, beating Norton by 5 percentage points.

While phishing is browser-agnostic, phishing protection is not. Bitdefender beat Norton by 5 percentage points, but its Windows cousin more than doubled that gap. Even Symantec Norton Security Deluxe (for Mac) didn't detect many frauds that its Windows edition caught.

Site Rating and Do Not Track

Like McAfee AntiVirus Plus (for Mac), Avira, Trend Micro, and several others, Avast marks up results in popular search engines with green for safe, red for dangerous, and gray for unknown. You can click to vote a page up or down. Simple!

Clicking the Online Safety toolbar button displays the status for the current page. It also lists all the elements on the site that can track your online activity, including analytics, social media, ad trackers, and more. By default, it doesn't do anything, but you're free to block any tracker or category. Websites are free to ignore the official Do Not Track header sent by your browser, but Avast's active Do Not Track feature has teeth. Kaspersky Internet Security for Mac offers a similar active Do Not Track feature.

Digging into the settings for Online Safety reveals a hidden gem: SiteCorrect. If you mistype a site name, this feature offers to change to the correct name. You can even set it to automatically make the fix, with no prompt. However, in testing, I couldn't tease it into action. I tried pyapal.com, pcmga.com, whitehous.gov, wallmart.com, and many others, with no reaction from SiteCorrect.

Basic Password Manager

Like Avast's Windows antivirus, this product includes a password manager. Where the Windows product invites you to install on Android, the Mac one suggests adding password management to your iPhone. On Windows, the password manager is integrated with the antivirus; under macOS, it's a separate app.

There's no limit on the number of devices, and you can sync your passwords between them all, macOS, Windows, iOS, and Android. Avast doesn't keep your passwords in the cloud. Rather, it uses your Avast account to authorize syncing data that's stored locally on your devices.

Once you've enabled syncing on a device, that device becomes an authenticator for adding more devices. The new device displays a numeric code, and the existing device gets a notification with the same code. If the numbers match, just click to approve. What if you lose all your devices? On installation, Avast sends an email with a recovery link; don't lose that email!

On each of your devices, you create a master password to protect the local password stash. The master passwords need not be the same, but who'd want the confusion of making them different? Avast offers advice on creating a strong password, with a color-coded line representing the strength of what you've typed. It's not easy to get all the way to green, but Avast doesn't require it. In fact, it accepted 'Password' as a master password.

Avast Download For Mac

Avast offers browser extensions for Chrome, Firefox, and Safari. When you log in to a site, the extension offers to save your credentials. If you come back to the site, it fills your saved credentials. Clicking the key icon in one of the fields brings up a menu showing all the credentials you've saved. And it handles two-page logins like what Google uses.

Avast doesn't use the typical menu of logins attached to its toolbar button. Rather, you click the button and launch the main application. Unlike the Windows edition, this is a separate app, not integrated with the main antivirus. Its main window is seriously tall and skinny, like something you'd find on a smartphone, and you have only limited control over its size. Clicking an item opens its details, with a link to open the site itself.

You can also use the password manager to sync and share secure notes between your devices. These are simple, unformatted text snippets, suitable for saving such things as locker combinations and non-digital passwords.

The left-rail menu offers simple icons to manage passwords and secure notes, and one to bring up the password generator. By default, it generates 18-character passwords using all character types. You can set the length anywhere from four to 30 characters using a slider.

Avast analyzes the strength of your master password when you first create it, but not when you update it. Avast Pro Antivirus on Windows can analyze your passwords, flagging any weak or duplicate ones. The free Windows edition used to include this feature, but it was recently enhanced and redefined as a Pro-only feature.

This password manager handles all the basic tasks and no more. Fancy features like secure sharing, two-factor authentication, and password inheritance aren't here. But you do get it along with the antivirus, at no charge, so if it does enough for you, go ahead and use it.

Worth a Look

AV-Comparatives certified Avast Security as an effective Mac antivirus. Impressively, it offers a network scanner and password manager, features often reserved for full security suites. On the other hand, the password manager handles basic functions only—nothing advanced. And while Avast earned great stores in my hands-on antiphishing test, that function currently works well in Chrome and Firefox, but not Safari. But the pros outweigh the cons. If you're looking for free Mac antivirus protection, give it a try, along with Sophos and Avira, and see which you like best.

For truly top-notch Mac security, you'll need to lay out some cash. Our Editors' Choice products in this realm are Bitdefender Antivirus for Mac and Kaspersky Internet Security for Mac. Both received certification from two labs. Both scored well in our hands-on antiphishing test. Bitdefender's AutoPilot mode means you can set it and forget it. And Kaspersky goes above and beyond feature-wise, with full-scale parental control, protection against webcam peeping, a network attack blocker, and more.

  2. Avast For Mac Review

Is Avast A Good Antivirus For Mac: Antivirus is the must have app for MAC. Due to the increased number of different viruses and hacking techniques, your personal data is always at the risk. Hacker can use your personal data for any type of illegal activities and you will found yourself in trouble soon. Sep 08, 2009  The only real reasons to have antivirus on a Mac are: 1) If your school or workplace requires you to have such software 2) If you want to be nice to your friends running Windows and prevent the spread of Windows viruses. Avast for MAC run smoothly on Mac OS X 10.5.x (Leopard), Mac OS X 10.6.x (Snow Leopard) and Mac OS X 10.7.x (Lion). It won’t run properly if you already have an antivirus protection installed in your MAC.

at

Avast Free Mac Security doesn't break a lot of new ground. As is the case with most free software, it does an OK job and — like popular free-to-play games — aims to pull money from your pockets after it's installed.

The one major perk of Avast Free Mac Security is that it can identify attacks in your email inbox, a feature that we'd like to see in all Mac antivirus services. At the end of the day, though, Avast's Mac malware protection rate isn't quite as good as its competitors', which is the most important part of antivirus software.

Avast Free Mac Security costs and what's covered

Avast Free Mac Security is free. It supports Macs running any version of macOS, as long as they have 128MB of RAM and 750MB of available disk space.

Antivirus protection

Avast Free Mac Security keeps Macs free of malware using traditional signature-based detection by unpacking Mac-specific file formats and scanning them for malicious content. It also uses its artificial-intelligence system to apply lessons from its user base to train its software.

Avast also thwarts PC malware on Mac, to prevent it from spreading on networks, and scans unopened ZIP files. It performs system protection scanning in the background, permits both on-demand and scheduled scans, and can scan your router to protect you against DNS hijacking and other threats.

Antivirus detection

Avast Free Mac Security's on-demand malware-scanning engine has a mixed record in recent lab tests. It stopped 100% of malware in tests conducted by Austrian lab AV-Comparatives in July 2018 and June 2019.

Results from German lab AV-Test were less consistent: 100% of Mac malware was detected by Avast in June 2018 and June 2019, but Avast caught only 96.3% of malware in December 2018.

That means Avast tied with Bitdefender Antivirus for Mac and Kaspersky Internet Security for Mac on the AV-Comparatives test (both hit 100%). However, it failed to match Bitdefender, Kaspersky and Norton 360 Deluxe on the AV-Test study, in which all three earned 100% scores.

Of all the Mac antivirus programs we tested, Avast Free Mac Security was the only one that flagged items already on our system as threats. Specifically, it found three email messages in my old, inactive, Outlook database that contained links to phishing websites.

Security and privacy features

Avast Free Mac Security includes Avast's Online Security browser extension, which automatically installs itself in Chrome unless you opt out, while Firefox provides a confirmation prompt to make sure you approve the extension. The Avast extension appears as a button that is green when you're safe and red if a site is potentially harmful. Similar flags will appear next to search results.

If you're wary of sites that monitor your actions, the Avast browser extension also displays a counter badge that tallies the number of activity trackers found in a website and provides an additional option to block social network-based tracking.

Not only does Avast scan activity on your hard drive and web browsers, but it also monitors POP3 and IMAP email clients, including Apple Mail, Thunderbird, Postbox and Airmail, and scans email attachments as well as email messages.

Avast monitors your computer and its network connections in the background, scans new files upon installation and lets you schedule scans. However, Avast Free Mac Security doesn't have any of the extra features offered by paid competitors, such as parental controls, a VPN service, firewalls or webcam blockers.

Performance and system impact

Avast Free Mac Security had a moderate impact on system performance, which we assessed by running our custom Excel VLOOKUP benchmark test, which matches 60,000 names and addresses on a spreadsheet. Our test machine wasa 2017 MacBook Air with a 1.8-GHz Intel Core i5 CPU and approximately 54GB of data stored on a 128GB SSD.

With Avast Free Mac Security installed on our MacBook, but without any active scans running, the VLOOKUP test finished in an average of 3 minutes and 38 seconds, 1 second longer than without any antivirus software installed. That's a passive system hit of less than 1%, and not something you would likely perceive.

Other antivirus products' passive system impacts ranged from 5% (Sophos Home Premium) to zero percent (Bitdefender). This is overall great news for Mac users: Most of the time, you'll never notice that you've got antivirus software running.

You would be more likely to notice the slowdowns created by Avast's active scans. During full-system scans, the VLOOKUP test finished in an average of 4 minutes and 59 seconds, resulting in a big performance dip of 37 percent. That's not as bad as McAfee AntiVirus Plus' 47% fall (the worst offender), although it wasn't as good as Sophos' 7% full-scan system hit.

Avast's full-scan completion time, which took an hour and 11 minutes on average, was on the longer end of scores but was not the longest we found — Sophos' 2-hour-and-56-minute time was the longest. Malwarebytes for Mac Premium's full scan took a miraculous 16 seconds, while Bitdefender closed its full scan in 4:25. Kaspersky (41:20) and Norton (25:49) fell in the middle of the pack.

Interface

Avast Free Mac Security may not be the prettiest antivirus app, but it provides a number of functions and options. Its main window shows users a Protected status, as scans are enabled by default. All other features, including on-demand scans, are located in a menu bar on the left.

Avast's main window presents users with their status — Protected or otherwise — and a 'Run scan' button that pushes you to Avast Cleanup Pro. You'll be confused by this abrupt switch of apps if you weren't paying attention to the fine print, and you'll soon realize that Cleanup Pro is a paid product that looks to tidy up your hard drive and costs between $2.99 or $3.99 per month.

How Good Is Avast Cleanup Reviews

After you click that Run scan button once, it changes to an Upgrade button for Avast Security Pro, which features anti-ransomware protections and Wi-Fi and network scanning. To avoid further confusion, click on Scans in the left-hand menu, which opens that section as well as other sections of the app, such as Reports, Virus Chest, Shields and Preferences.

In Scan, you can select from a number of different types, such as scans of custom directories, scans of removable volumes and scans of your home network. Avast also includes scheduled scans, an increasingly rare option these days.

Clicking on New Scan presents a Start button for activating a Quick Scan and a Change Scan Type button to switch to a full-computer scan.

You'll find database updates and analyses of scans performed on your system in Avast's Reports. Avast places files it flags as malicious into the Virus Chest quarantine section, where you can delete or restore them (if you think Avast is mistaken).

Open the Shields section to see real-time analysis of scanned files. Annoyingly, if the file directory is especially long, Avast won't give you the full directory, so you can't go look up the offending file for yourself. You may not need to, but we'd prefer to have the option.

In the Preferences tab, you'll find options to change the frequency of notifications, system updates and scans. Here, you can also disable hard-drive, email and web protection, although Avast wisely makes you enter your system password first. Additionally, you can disable Avast's menu-bar icon from this window (it's under Miscellaneous).

If you create an account with Avast, you can check the status of any systems you've logged into in the Account tab as well as at my.avast.com. Avast's menu-bar button provides links to open the main interface window, see current activity and application information, and review previous notifications.

Installation and support

To install Avast Free Mac Security, you open Avast.com and click Download, which will place the installer DMG on your Mac. (Thankfully, you won't have to go through download.com anymore, an annoying part of the previous model.) After you click through the end-user-license agreements, the installer will download more files and install Avast.

No restart is required, and the whole process took about 2 minutes for me, which felt about normal. In the middle of the installation, you get the option to not install Avast's unlimited Password Manager and the company'sSecureLine VPN client. The Avast Online Security browser plug-in is free, but you get only a seven-day trial of SecureLine VPN service, which otherwise starts at $60 per year.

To get technical support, click Help in the menu bar, select Avast Technical Support and then select Contact Help to open Avast's Support site. Here, you can find a FAQ, ask for help in the forums and call a customer-support line that will provide free advice for installing, configuring, updating and removing Avast.

Avast For Mac Review

If you need more help than that, Avast offers paid support starting at $79 for any call that isn't related to removing a virus or malware, or at $119 per call for virus-related calls. For more support, you can spend $199 for a year of unlimited service, or $10 per month plus a $99 setup fee.

Bottom line

Avast's email scanning gives it an edge over competing Mac antivirus products. It needs such an advantage when the rest of its package is such a mixed bag.

Not only does Avast's software continually push you to spend money on additional services (unlikely if you've already chosen to use free antivirus software), but its malware detection rates aren't great overall.

If you're going to pay, you should instead choose Bitdefender Antivirus for Mac, which gives you excellent protection and a low system impact for $40 a year. If

you'd rather not pay, then Avast is the best free option, but only because Sophos Home, which has a more full-featured free tier, has undetermined malware-protection abilities on Macs.
