Got a call from a "Microsoft Certified Engineer" stating that my computer had been sending warning information to Microsoft regarding a Virus and that he wanted to connect to my PC to fix the issue. They claim to be calling from a company called AskPCExperts.com(which is a legit company), but M$ would never contact individual customers regarding a possible virus on your PC to start with. From what I have found, they connect via TeamViewer to your PC and then supposedly show you stuff and possibly upload virus, etc....
Caller: David (no last name)
