Microsoft phone scam

I was talking to a friend of mine yesterday, and she started complaining about a series of phonecalls she's getting from a firm in India. They claim to be working with (maybe for) Microsoft and try to talk people into logging onto a website so they can take control of your computer. I suspect probably to install a keylogger or to get passwords. Fortunately for my friend, she became suspicious and unplugged her PC, at which point the person on the phone started swearing at her.

She contacted BT who said they've had a ton of complaints about this firm, but, as they're based outside the country, BT can't do anything. At this point, the firm in question is phoning my friend almost daily. As she said, they've got to know by now that she won't listen to them, but I guess hope springs eternal.

So if you get a phonecall from people claiming to be with Microsoft, ignore them. This might only apply to the UK, but I wouldn't be surprised if they're ringing other countries too.
