SCAM WARNING: 'We're calling From Microsoft. You have errors on your computer...' If you have any phone calls and hear these words... it's a scam call and the caller will try and persuade you to switch you machine on, press certain keys, gain access to it, and control your computer from afar. They also ask for your card details.

They seem to be doing the rounds at the moment. Needless to say, don't have anything to do with them. More details on http://tinyurl.com/4yq3u4r
