Didn't recognize the number do didn't answer.....I see it was a good thing I didn't answer

I trolled this number and the guy called me a moth******er xD

It is a scam of course.  They will try get you to let them "fix" your computer for a fee

Microsoft make great efforts to warn against ALL such calls at http://www.microsoft.com/security/online-privacy/avoid-phone-scams.aspx

These scammers have been calling my number 5 or 6 times over the last day or so.. I don't answer them..Now they are using invalid telephone # IDs..Wow these people are persistent buggers..  

A male with a strong Indian accent has called four times today.The first call we answered.  He identified himself as "Frank" and said he was calling from Windows about my computer.I hung up and did not answer repeated calls.This number cannot be blocked on our system.
