Once again, UK Bob to the rescue! I just started using AVG and I'm pretty happy with it. I also have Norton Internet Security 2005 along with Ad-Aware and Spysweeper for the adware/malware and that seems to be doing the trick for me. I do believe (and I think most will agree), it's important to run at least two programs of each (anti-viral and spware/adware), because one will more than likely catch what the other missed.

If you're interested in AVG, you can download it here:

P.S. UK Bob, your log freaked me out, I'm getting Peer Guardian!
