That means you should choose a program from a reputable developer with a reasonable and transparent privacy policy. But you probably have additional devices, right? Malware, phishing, and other threats also affect Macs, Androids, and even iPhones. Some companies offer multi-device subscriptions so you can easily protect yourself with free antivirus software for Mac , cybersecurity for Android , and mobile security for iOS.

Most companies offer advanced features, add-ons, and customization options in their paid products. But our above list of the best free programs contains options for excellent virus and malware protection — and many include great features in their free versions, too.

Microsoft has put resources into trying to make its built-in solution the best free antivirus for Windows But while it has improved by leaps and bounds in recent years, Windows Defender is still not as good as many third-party options out there, like AVG, Avast, Kaspersky, and BitDefender.

Beyond test results, there may be other issues with relying solely on Windows Defender. Absolutely not. Product and OS updates often include patches that plug security holes. Ignoring security updates can make you far more vulnerable to malware.

With these persistent limitations to Defender, most AV experts still recommend you opt for one of the best free anti-malware software options on our list above. These labs have the resources to test thousands of real, active malware samples of all kinds viruses, worms, ransomware, zero-day exploits, Trojans , botnets , backdoors, and more and to perform the same tests on different antivirus software simultaneously to guarantee accurate comparisons.

Trend Micro's software earns high marks from AV-Test -- scoring percent of detecting 0-day attacks and widespread viruses and malware. And Trend Micro does a good job of not taxing system resources. It earns top scores for usability and offers solid virus protection. And its Android antivirus gets top marks in third-party tests. Because the company has been in the news the past few years, let's talk about Kaspersky Lab -- specifically about the federal ban that blocks US government agencies from using Kaspersky products.

Based in Moscow, Kaspersky Lab has for years produced some of the best antivirus software for business and home customers. But in the US government prohibited Kaspersky software on federal government computers because of alleged ties between Kaspersky and the Russian government.

Notably, the ban does not apply to its consumer products. But, like China-based Huawei , the question remains: If the federal government doesn't think the products are safe enough for its own devices, should consumers avoid it as well? In a statement sent to CNET, the company said, 'Kaspersky Lab has no ties to any government, and the company has never, nor will ever, engage in cyber offensive activities.

Kaspersky Lab maintains that no public evidence of any wrongdoing has been presented by the U. Government, and that the U. In Kaspersky's favor, it continues to earn top scores and awards for virus and malware detection and endpoint protection from independent testing labs. In the end, even though no one has ever publicly produced a 'smoking gun' linking the company to Russian intrigue, we think any of the options listed above are a safer bet.

And, if you are a US government employee or work with the federal government, you'll want to steer clear of Kaspersky.

You want antivirus that can successfully identify these unknown threats without flagging too many false positives. Light on system resources. You don't want antivirus that taxes your PC's resources.

Protection for other platforms. Microsoft is by far the biggest target for viruses and malware. But Android is second, with the largest threat coming from sideloaded apps -- those you install outside Google's Play Store. Google said in the last quarter of , 0. For those installed from the Play Store, the number drops to 0. To stay safe, we do not recommend sideloading apps, but sometimes, like with Fortnite , you might want to.

In that case, running virus and malware protection from a trusted security company is not a bad idea.
