This guy said he was calling from "Windows." Said they had received remote information about "bad things" that were downloaded on my computer when I was online. Wanted me to go to www.ammyy.com -- where they wanted free remote desktop access to my computer. I kept doubting this guy was calling from Windows. He spent a great deal of time trying to convince me otherwise. He even gave me a second number -- 804-435-5332
-- which I could call between 6pm-7pm to verify their identity! This is really, really scary.
