>>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?

I adhere. I've been running AVG free and it feels a lot more lighter than Norton, yet it is far less noticeable and it has proven as effective or more. Not to mention it is free for personal use.

My vote for AVG.
