avast! Antivirus

Can burn in hell. I downloaded it in the hopes of removing the BSODs that I keep getting from certain sites. Originally I only got it from rapidshare, then uploadmirrors, then when I got it from mediafire I decided I'd do something about it. So I got avast! Antivirus and installed it, and let it scan my computer and do its magic.

I did not expect the bloody thing to completely screw my computer. It cleaned a lot of files, but when I opened up Windows, it kept freezing anytime I did anything.

In the end, I uninstalled all 3 of my Antiviruses (ESET, Ad-Aware and avast!) and now my computer is fine. Need a recommend for a nice, totally free Antivirus that is not AVG.
