Help please

I have a problem, I've got a big annoying error message and it won't go away. It says "Spyware detected on your computer, install an anti-virus spyware remover to clean your computer" then it says the bugs are called Win32/Adware.Virtumonde and Win32/PrivacyRemover.M64. I've ran my Ad-aware anti spyware thing twice and it doesn't help

YAY! after sending half the afternoon trying to load Spybot (dial-up sucks)it finally worked. The annoying warning message is gone and so is the blue desktop background.

Thanks 4chan, I don't know why nobody likes you, you're good people. (or atleast you know what the fuck you're doing anyway I sure don't)
