Scam call with spoofed number. Do not call the number they give in the message. This same number has been used for dozens of different scams already. The IRS does not call people and even if they did, they would ask for a specific person, not just have a message for anyone who answered. It wouldn't be a recorded message either. I'm sure these scammer's parents are so proud of how they get by in life! Then again, some of their parents probably taught them how to scam people, because it is easier than becoming a productive member of society.
they claim they are from microsoft, and that you're computer has been sending out messages and may be corrupted. They want some serial number or something off your computer..told him I wasn't near the computer, he was very persistent on a specific time to call back. Likely a scam.
