I received a call from 806-319-9507; the person claimed to be a certified Microsoft technician. He stated, "The Microsoft servers have detected an error on your computer. I will guide you through the repair steps needed to correct the error." I let him babble on about being a computer technician and that he needed me to fix my computer. I disconnected and called the number back. It was an answering machine designed to record messages and it was full and could not take any more messages.
