I keep getting this pop-up to download "IE Defender" because a "Trojan.Zlob-x.a" infection is affecting my computer. This pop-up is truly annoying. I've attacked it with superantispyware, SmithfraudFix, Vundofix, and RogueRemover. However, this bastard keeps popping up. I've tried cleaning my files while in safe mode with hidden files shown, and that hasn't worked either. Any suggestions? This this has really crawled up my ass.
