I have seen many threads on the site, and am so far unable to solve my problem. I clicked on a VideoCodec that I knew I shouldnt have and ended up with the Critical System Error popups "You have been infected with the Win32.TrojanDownloader.Zlob" I've run and updated Norton 360, Ad-Aware, Spybot S&D, and even downloaded and paid for Stopzilla none of which are catching this. It is affecting IE 7, but doesn't seem to affect Mozilla. My Windows media player will not work at all. Keeps saying log off windows log back on and start which does not work. Can anyone help?
