Said they were Microtec, partners with Microsoft, and that they received information from my pc that I had downloaded a virus. He said his name was David Smith(sounded like he was from India) and the purpose of his call was to help me fix it. David wanted me to log onto my computer and he would help me.
I looked up Microtec and did not find any matching information. David also gave me a "Toll free number", 855-593-3163. This is a toll free number, for him, not me. I will not be calling him back.
I did not and do not feel good about the call. I did not try to call back either number.
