SCAM ALERT!  While I was taking a nap these people called and my husband thought he was the tech that was checking our computer and turned all our desk computers over to them. I got up and saw what was going on and didn't like my husband's explanation, so I looked at caller ID and checked google, with my laptop, and found they were a scam. Yelled to my husband who told the guys his wife was calling him and they let him off the phone. I told him to unplug everything including modem internet everything. Which, bless his heart for once he obeyed, and after calling a friend who fixes computers he went and deleted the files that contained the instructions to share his computer with those scammers. Whew! My husband has early dementia and this was very scary. Don't let them do this to you.
