Chances are that you or someone you know has gotten a call from someone claiming to be from "Windows technical support" phoning up to tell you that you "computer has a virus" and offering to remove it for you - for a fee. Now I don't know about you, but I've never had the time (or patience) to play along, so I've always been curious to find out how the conversation pans out.
