I got a call from Mack saying that he was from Microsoft. When I asked how he got my number, he said that he got it when I bought my computer. So I asked him how he knew I had a computer. He again said he knew from when I bought a computer. I then told him that I have two computers in the house but I didn't buy them because they are work computers. He obviously had an East Indian accent and proceeded to speak. I cut him off and asked what his next lie would be. He proceeded to stumble over his words and I hung up.
Same deal here. Supposed problem with my (non-existent) Windows computer. Obvious phishing for personal information, or attempt to get me to use my web browser to download malware/virus.
He called me at 10PM last night. He kept asking me to write a number he was giving me. It was supposed to be a "Customer License" number only he and I had access to. He told me my computer was sending him "errors and warnings." Eventually I hung up.
