Yes. Kaspersky, Norton, and BitDefender are currently working with their full capabilities (AV, HIPS, Firewall, Proactive Defense, SONAR, KSN, etc.) on Windows 8.
I am using Nod32 v5 on 32bit windows 8 pro without any issues.As mentioned in previous posts, set the update channel to pre release updates.
Cheers.....just saw that now :-( The Avira guys need to get their asses in gear and get this working!!
Microsoft's built in antivirus is not as good as paid antivirus engines ....better to use a good antivirus software with windows 8 .... i prefer kaspersky internet security ...but i haven't tested if it works with windows 8 or not ..and kaspersky is going to launch new version 2013 which will be compatible with windows 8 ...so just wait 4 it ..
I use Kingsoft Antivirus. Usually use Norton but the newest is still in Beta. any thought on Kingsoft Antivirus
