Caller spoke a middle eastern accent and claimed to be from Microsoft and receiving error message from my computer. This is impossible as even Microsoft has no business seeing anything from my computer unless I authorize the computer to forward error messages on. However, saying that, I have not received any error messages, have not submitted any to Microsoft for review.
IN MY OPINION: This is a scam of some sort to try and gain access to your computer. DO NOT allow anyone access to your computer unless YOU yourself have called a reputable company such as Microsoft.
