AV-Comparatives releases list of working consumer AV programs for Windows 11 September 28, 2021 https://www.av-comparatives.org/av-...-working-consumer-av-programs-for-windows-11/
Avira has a Windows 11 page up, but no specifics: https://www.avira.com/de/home/security/antivirus/educational/windows-11 BullGuard, right now doesn't support Windows 11.
Most vendors should be fine by now. If not, they have a week to get it together. I expect several products to gt an update next Tuesday.
I'm actually surprised any vendor is not supporting Windows 11 a week before its release. This is especially w.r.t. things like the right click context menu.
There are a lot of vendors that refuse to officially support a Windows version before its official release even if it works.
Kaspersky comes to mind for me. I haven't been on the forums of either for a while but historically their product usually works in advance of release but they won't even allow questions or comments on running it on an upcoming release until release day.
F-Secure also ready for w11 https://community.f-secure.com/safe...new-in-f-secure-safe-for-pc-internet-security
