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

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.

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

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

Reasons to Buy
Moderate performance impact

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 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.

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.
