What is, in your opinion, the best protection(anti-virus,anti-spyware, etc.) thats FREE? The only thing I got right now is Avast! Anti-virus and I used to use Ad-Aware SE Professional v1.06 but how is the new 2007 free edition? I heard of AVG and I used it like 4 years ago and it was sh*t so how is the current one compared to Avast!?
