Looking for a completely free antivirus for Windows without any licensing fees?
Microsoft Defender functions properly. I've used Sophos Home for many years. Just register using an email address. https://home.sophos.com/en-us
It's all Norton Lifeguard. They control Norton, Avira (and therefore Bullguard) and Avast (which also includes AVG). The only drawback is McAfee. Twenty years ago I preferred Trend Micro, and about a decade later Eset Nod32 was top-notch. In recent years Kaspersky and Bitdefender dominate the market. Add F-Secure and possibly Bullguard. Those four might be the best options besides Defender.
Windows Defender stands out as a solid option without needing an antivirus subscription. Its main drawback is its tendency to reject whitelisted false alarms, which can happen more often with very outdated software.
They seem to be in the process of merging. AVG continues to perform well and has consistently earned praise for its security and protective features. When compared to McAfee, it's like comparing MKHD to The Verge.
