Browser extension hijacker. How to get rid of it?

My IE has been hijacked. The hijackeer seems to install a browser extension type of add on to my IE7.

I can’t seem to get rid of it through IE interface. And I can’t seem to find its entry in HijackThis.
What can I do?

Ha I forgot to run Hijack this with admin rights. Now begone you mole

Hmm whenever I close IE7 32 bit Vista is saying that it had to close IE. Something about DEP protection. Weird does anyone have any idea how to stop this Vista pop up? I’m reluctant to turn off the DEP protection.
