WTF is Winfixer and how do I get rid of it??????????????

[teddyFBI]

I don't understand how this happened.

I had some really weird stuff happening w/ my computer, so I reinstalled Windows. Everything went just fine, except for the fact that now I have something called Winfixer that won't go away -- it steals my browser window sometimes, but more often than not it opens up a new browser window that goes to WinFixer's home page and sometimes popups up a prompt box asking me to download it.

WTF is this spyware, and how do i get rid of it??

What I don't get is how this is already infecting my computer immediately after a Windows reinstall...I figured it would have cleared any spyware from the machine...i haven't even downloaded anything since the reinstall...
