someone using this number called me three and four tumes and tried to scam me into believing they were with Microsoft and had deteced a hacker in my system.  I went as far as allowing them into my system. They then wanted me to pay for a "clean up" program.  I had the recording of the phone call and they lies they told me online.  I told them I would call them back and then contacted Microsoft and discovered (DAAAAAAAAAAAAAAAAAAAAA) that it was a scam.  I could tell with the noise in the background it was some kind of tele-marketing room with lots of noise and feedback on the line.
