We spend a lot of time looking at the best paid antivirus suites on this site, but we don’t spend a lot of time talking about free antivirus solutions. Part of the reason is that the free versions are based on their paid counterparts.
If you see a paid version you like that offers a free version, you can safely assume the antivirus protection level is similar, save for any specific malware types the free version doesn’t cover.
To create this list of the top free AV programs we looked at the top mainstream antivirus suites for Windows 10 and selected the ones that offer a free version, as not all of them do. After that, we looked at how well these suites performed in third-party detection tests. We also made sure they weren’t resource hogs, because the last thing you want is a piece of free software slowing down your PC while running in the background.
