just had a call tonight from a guy from India who knew my first name, surname and gave a credible story about my PC being slow and windows sending error files to Microsoft and they have seen the errors and would help me clear this up.
He talked me through looking at various things on the PC and then asked my to go to an internet site WINDOWSONLINECARE.CO.UK and instructed me to click on an icon there. I refused as I didnt know who there were.
Good thing I did as it is a scam to get onto your PC details here
They even phoned back about 10 minutes later to try try again - I wasnt very polite 
Dont think anything has happened to my PC as I only went to the website and never clicked on the icon to give them access - anyone techy out there who thinks I've got a problem let me know.
