I followed the link that RejZoR gave but was unsure when I got there exactly what you have to download.
Also spiritsongs, honestly I have turned it off and just monitor it myself, but I just can't help reading everytime somebody posts this problem.
Limetreebloom I have also switched off "Windows Management Instrumentation" in services, then restarted my computer and started it all again. Sometimes this will fix it but only for the day. That is why I used to just restart "Security Center" for a daily fix.
But as spiritsongs always says, turn it off completely and monitor it yourself. You never know the next Windows full version of Internet Explorer may fix things, or on the other hand it may make things worse, who knows.
