Spyware...

I originally thought I had a virus, but when I searched, "Win32.IEmonster" turns out it's a fake threat that makes you think you have a virus and causes you to purchase their virus protection.

The damned program doing this is Green AV. I don't know how it got installed, but I can't figure out how to remove it from my computer. All the spyware scans I use will look for them, and make me wait for two hours before they tell me that in order to remove the threats I need to purchase the software for x amount of money.

Anyone heard of "Green AV" and know a way to get rid of it?
