Some man called me from this number and said he was with Microsoft and that my computer sent him something saying that it was having trouble with something that he wouldn't tell me what it was. He wanted me to push the window key and the letter R and that would help show me the problem or help me fix the problem. I told him that I wanted to call the number back to see if it really was Microsoft but when I called it back nobody answered. So I did not push the buttons and just left it as that.
Same MO today...heavy foreign accent saying I had bad code in my computer....Said he was certified Microsoft technician and that he was telling me the truth because he had given me his name and ext. he did not understand why I wouldn't cooperate with him when he wanted me to run a program
Somebody claiming to be a Microsoft tech called saying my computer was causing errors on the Internet. I have Apple computers. When I responded [***] he got upset. :)
