Okay, I have a virus. Or maybe a couple viruses.

AVG doesn't seem to want to get rid of them. Its currently doing a scan right now again, and I'm going to see if that gets rid of it. I'm running an Ad-Aware scan as well. The problem is it keeps popping up internet sites. I once got an un-wanted porn popup.

What are some good and effective ways to beat the <img src="/xxx.gif"><img src="/xxx.gif"><img src="/xxx.gif"><img src="/xxx.gif"> out of viruses?
