Just finished removing some malware from my computer, when I noticed another infection. While visiting what I would call "safe" sites (school website etc.) I get a flash popup for some very offensive ads to 12webcam.com. They appear in the center of the browser window near the top. I only run Firefox so I do not know if it would happen on IE as well. Hijackthis log below. Any help appreciated. Thanks!
