hxxp://seventorrents.com/

I’m tink this site are infected its want to accep some wierd thing that microsoft did send out and try to open something

If you see that, you are already infected

I agree with the previous poster.
Its not an exploit on this site.
It’s adware or worse redirecting from within.

Download hijackthis, do a system scan and save a log, but don’t fix anything yet until told to do so.
http://free.antivirus.com/hijackthis/
If you have vista or 7 you will need to go to where its installed and right click the hijackthis.exe file and choose “Run as administrator”.
If you have trouble running it, rename the file to 'helper.exe" without quotes.

Download, install and update malwarebytes antimalware, get it from here.
http://www.malwarebytes.org/mbam.php
get the free one that requires manual updating and update and scan with it.
Remove everything it finds.

Post the hijackthis log along with the malwarebytes antimalware log back here when you have done this.
