Like others, got multiple calls (with no message) and finally picked up; was a heavily accented man claiming to be from Microsoft and wanting to protect my computer—otherwise Microsoft would be shutting it down in a few days. Which computer? I asked. "Your home computer," he said. Which one? "Your Windows computer." I don't own a Windows computer. He hung up.
Indian accent calls all the time, says it is about my Windows computer. I told him I knew it was a scam and to stop calling. He said not a scam but I told him we were on the Do Not Call Registry and I had already reported him and would do it again which I just did. Calls on my home phone so not sure how to block him, so far no calls on my cell.
