I have an AT&T DSL that came with McCafee Security Suite, and my computer has more bugs than the Amazon rain forest. Every time I do a google search, I get redirected to other sites. My task manager has been disabled, my registry has been corrupted. I've used system restore, but the bugs seem to follow me back in time. I've also tried various trial versions of other antivirus and anti spyware software, with little success: AVG, Ad-Aware, Super AntiSpyware, Spyware Doctor. I've also switched browsers from Internet Explorer to Firefox, but that doesn't help. Any suggestions on how to get rid of these bugs. I'd prefer freeware, since I don't have much money to spend on this.
