I Ask For Help I Guess I Catch A Trojan :(

Cheers

I am a stupid person when it comes to computers. I will write you about what happened. Near the afternoon I sent an im to somebody I know well. She sent me a link to something weird clip. I have opened it and downloaded a codec in order to watch the videoclip, it went ok but after an hour or so I got many popups with banners all over my screen

Any advice any of you?
