Kaspersky Internet Security & AV = Not compatible with Windows 8.

The common filenames for the program's installer are bdmcon.exe, bdagent.exe, bdlite.exe, devsetup2k.exe or obk.exe etc.

The latest version of BitDefender Free Edition can be installed on PCs running Windows XP/Vista/7/8/10/11, 32-bit.

Additionally, they haven't been doing well in independent AV tests and some sites report that their performance impact on the system is high unlike the old days where they were super lightīitdefender AV = absolute crap, although it gets 100% in all virus tests I've seen, it by itself is a virus and causes a lot of trouble starting from slow browsing on the web to many false positives The following versions: 12.0, 10.2 and 8.1 are the most frequently downloaded ones by the program users. NOD32 = Not yet compatible with Windows 8.1 and even though their Beta version 7 IS compatible, I don't want to install a Beta software. I have a 3 year license for Eset NOD32 and a 3 year License for Kaspersky Internet Security and a 4 year license for Bitdefender AV but although the last 2 score well in AV tests, they have a lot of glitches. Is avast! Free Antivirus compatible with Windows 8.1 yet? What is the exact version that I need to be downloading? I just did a clean install of the RTM Windows 8.1 圆4 and would like t know before I wreck my system
