They identified themselves as part of the Windows Update Team. They wouldn't mention or say Microsoft no matter what I said to him. I'm an IT Tech and this guy who didn't speak very good English went on to tell me that suspicious IP addresses were accessing my computer. I informed him that my Sonic Wall (firewall) keeps logs of all incoming and outgoing traffic on my network. I asked him what the IP addresses were and I'd be happy to check my logs needless to say he was at a loss for words. He said he needed me to log on to my computer and he could show me (Red flag for any non tech users) never let anyone access your computer unless you know them. I went on to ask him which computer was compromised since I have 5 and various tablets & phones. He said the one you updated recently. I told him that would be zero then. I asked him for his rebuttal and he started to get frustrated. Anyways do not fall for this scam.
