called me 3 times today and left blank voicemails. Finally answered and the woman said she was calling about my "windows computer". I asked her to clarify which computer -- she kept saying "windows computer" and then said "your home computer". I don't have a home computer so I immediately asked her to stop calling and I blocked the number.

Same basic story as Jay, but it was a man calling with a strong South Asian (probably Indian).  Left two message before i answered.  Said he was calling about my windows problem, that there was an issue with it  that he was going to fix, as we spoke.  Clearly a scammer.

Was clearly a scammer -- said he was with "Windows Computer" wanted to fix my computer because it had issues.

A woman called about my "windows computer".  Was very difficult to understand and could hardly hear her.  

Same as others. Woman caller says she's receiving messages from my windows computer. I asked which windows computer. She repeated windows computer. I teach Intro to Computers on the college level. I asked her for the IP address. She gave me a bunch of numbers nothing like my address. Told her she needs to be smarter to know what she's scamming and don't call again.
Idiots.
