On two occasions in the past few months I have received telephone calls from some Indian gentleman who says he is from a group called "Windows Care" and that he wished to advise me about problem files that this group has detected have been uploaded to my PC.
The reason I am suspicious is that he always asks for a Mr. X, which is not my name but is my partner's surname and the phone is registered in her name. Obviously these people are using the time honoured telephone hit list.
Had he quoted a product code, a licence number, or even an IP address then I might have have been a little less suspicious although the fact that my anti-virus and anti-malware software has detected nothing would have kept me sceptical.

Has anyone else had any calls from these people?
