Just received a call from a woman with a strong Indian accent, who said she had an urgent message for the main user of the Windows computer in our home.  I told her that he was still sleeping.  She was insistent that she speak with him about an urgent matter about the Windows computer. I told her she could call back in an hour - boy is she going to be sorry if she does!

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

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..  

caller id'd - didn't answer - from other posts I see it was a good thing I did not answer - Is this one of those deals that if they get you on the line you are charged for the call - it looks like a foreign number - can't this be stopped?????

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

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