I've read about this scam, and it just happened to me. I got a call from someone (with a thick accent) saying he is with "Geek Support" assisting Microsoft in helping customers solve issues with their computers. He asks what OS I am using, what wireless internet I use, what antivirus I use. I told him "none of his business" and that I have read about this scam (they try to talk you into allow them to remote into your computer to "fix" things). He tries to tell me they are legitimate and tells me to go to their web site. I told him I could create a web site saying anything I wanted to. He keeps trying for a while, and I finally told him to get lost.
