Appears that this is a fraudster. Starts by saying that as a Microsoft licensed specialist, my computer is infected with "Errors" which will slow the machine, and eventually stop it shortly. Wants to sell me software - Would the software be infected, or does he want my credit card details?Called me 3 times even tho' I showed no interest.............

When people call you using Skype that number comes up.

I got the call, they phone in the morning it starts about 9:30 and they keep calling until they get you to answer. If you call the number back it is not a real number, the guy said he was calling from Microsoft about my computer and told me to go to my computer and do exactly what he says to it, of course I hung up on him. He sounded like he was from India and it was a noisy connection. I think it's people trying to steal identities and/or trying to get your personal info or banking info.

Constantly called cellular phone, probably over 10 times during the night.  If no answer, the number becomes "unknown" after a few times.

i live in the 519 area code area, when my friend from Pennsylvania calls me using a long-distance phone card this number shows up on my called ID

Same thing except it was a friend from his house in Pennsylvania. I too am in 519 area.
