Some individuals a calling saying they are from Microsoft Tech and you have a virus or such on your computer and you need to buy their firewall program for $300.00. or your computer will no longer work. This is just a scam and they tried it on my grandson in Tenn. I told him not to talk to them and do not get anything from them. I connected with his computer, and found nothing wrong. Just wanted to say how this gets my gal when idiots call up and get unsuspecting people all upset with their crap.
