Don't worry, it's a scam. The police have nothing to do with it. It's just a bunch of crooks using virus software to get money out of you by pretending to be the police, and hoping to scare you.
Ignore it completely. Certainly do not pay. If you don't already have full anti-virus software, then get some and run a full scan and clean-up.
Yet again with this question. What you're seeing is called ransomware, a virus that takes over your computer with a fake police warning and requires you to pay the fine/ransom in order to remove it and unlock your computer. Use an uninfected computer to look up instructions on how to remove it.
Hey there,
The first thing to do to speed up pc and get rid of malwares and viruses is cleaning the registry with a program like CCLeaner http://bitly.com/UrAS6C
Give it a try.
BIG SCAM> Google Met police scam, thousands have had it. You now have to try to get the virus off your computer. It will tell you how.

Sounds like you were watching porn and you have been caught doing it. You can try to prove your innocence to the police when they visit you in due course.
I was moved to one site and it said that it is British police and I broke the law by viewing child pornography or zoophilia (I did not) and downloading something. It says all consequences and says my browser and computer has been blocked (it is not) and I have to pay 100 pounds.If it were police, they wouldn't use the stupid site, wouldn't they? It showed my IP adress and I don't know ;o
