>>>I've used Symantec in the past, but it use too much resources IMHO. I currently use Avast, but I have some doubt about it's efficiency. I ran a complete scan this weekend and it found 5 virus in my system. My question is: why did they get in in the first place? Isn't it the job of the antivirus of stopping the infection before they get in the system?

From what I understand, AVG has stopped issuing pattern updates for v6 since the end of last year.

UPDATE: I see on their main page they have extended pattern support to February 15, so you have a little time left :)
