Help! I have a fake windows security center virus?

Let me start off by saying what actually happens with videos. Whenever a
page comes up that has a potential video on it, ones in which you can
click a play button, my computer freezes up immediately. I ran a virus
scan and there are no viruses. Literally, a second after the page comes
up it freezes and the "program is not responding". It was working fine
early today. Now that I think back though, a message came up that was
asking for me to grant permission or something and I may have clicked
never but I can't remember what is was asking for etc. Are there any
common downloads I could do or any security options that I can get
around? 'iphone unlock' (http://unlockiphone22.com)
