Malwarebytes — Minimalistic antivirus with on-demand scanning. Sophos — Good real-time scanning with remote access for 3 PCs. Comparison of the Best Free Antiviruses for Windows in Here are a few of them: Avast. While Avast — and their subsidiary antivirus company AVG — continue to offer two pieces of widely used free antivirus software Avast Free Antivirus and AVG AntiVirus Free their repeated privacy violations have caused too many concerns. However, if asked to recommend a freeware antivirus Antivir comes with too many caveats and explanations the nag screen, the email scanning non issue.
It is easier to recommend Avast, as it provides comparable protection and performance, and is an excellent product. AVG is my third choice. It also provides excellent protection and has the edge with respect to the least number of false positives, but its performance and detection rates lag behind the other two.
The programs tested were subjected to 1,, instances of malicious code collected between Apr Apr The reason: any malware collected prior to this is considered fairly well known by now.

For Antivir, the freeware version is different in that it does not perform email scanning and displays a nag screen, but these have already been addressed above. Also, as of this writing the newer version of Antivir includes an antispyware component.
