I don't own any of those, except for Need for Speed II (yes, the second game in the whole series), and I haven't bothered to install it because I really don't have any interest in it.
Also, I did have 3 free AVs running on my laptop without much conflict, just to test which ones were the best. Avira's decent but a pain with its heuristics detection, Avast! is pretty good, you just gotta have enough resources, AVG sucks, and Microsoft Security Essentials manages to be both competent and lightweight.
I ditched all of those in favor of Microsoft Security Essentials. (b'-')b
