Now you've done it.  Logged in as administrator to browse the web and download illegal content off the internet.  Now you have this pesky ? in your tray, asking you to buy this software to remove spyware.

I recently had to fiddle with this stuff... and I found http://www.bleepingcomputer.com/resources/link244.html worked well for me.  roguescanfix_setup.exe can be downloaded at the bottom of this post as well.

Enjoy.
