How do I get rid of the "Windows Antivirus" spyware/virus?

I have the "Windows Antivirus" spyware/virus. The one that has the little caution triangle in the corner and says "Windows has detected spyware infection..."

I did a search on Yahoo! Questions and tried all the suggestions. And so far I have downloaded Ad Aware, Norton, and Super Anti Spyware and none of them got rid of it!

How do I get rid of it? I can't do anything on my computer with this darn thing on here!!!
