I was on AVG in the past, but Nix was dead on, it's slow and bloated now. It slows down startup too much and eats more system resources than what you'd expect when it scans your system. I moved to NOD32 after. Better in a lot of aspects, really. As a regular user you won't run into it until it tells you that it's already DONE updating its virus database. Nice.
