I got a call from (706)805-1795 telling me they are microsoft and my computer is going to be turned off because bad stuff. They knew my name and zip code. I hung up. Scam.
Totally ashamed to admit it, but I got the same call two years ago and fell for it. They got remote access to my computer, as I sat here and watched them take over my computer right in front of my eyes (mouse pointer moving and clicking without my control) and lost $300 to boot. :( Glad you didn't fall for it!
