Scam call.  "Amy" from "Microsoft Technical Support" called to let me know my computer was infected with a virus.  I knew it was a scam right away, but played along.  She wanted to confirm who she was speaking with and gave my mother's name instead of mine, which is a hoot because my mom doesn't have a computer.  I told her I knew this was a scam and she started screaming at me that it wasn't.  I said okay, if it's not a scam, tell me what you're going to do to my computer.  She hung up on me at that point.  At no time did they gain access to my computer or any of my information, so their scam failed.
