Computer Scams

Hey folks,
Please watch yourselves there is a company phoning round people telling you that there is a section in your windows pc that is corrupt and that you'll loose your files in a week or so. We have just had this phone call and i called them up on it asking them how they know that there is a problem with my computer and that i don't even use windows and she hung up on me.
Please don't fall for this scam, you will not get a call from windows!
