Just received call from "Shaw" or "Sun" Communications". He had a strong accent and I couldn't understand him very well.Said he was my service provider and he was receiving error messages from my internet. Funny thing. I don't have an internet provider.  I offered to let me talk with our IT guy and he hung up.

It's a scam.  Here ya go-  http://www.snopes.com/fraud/telephone/microsoft.asp

I keep getting calls from this number when i call back its a busy signal  its comes in between 9pm an 10 pm
