Goin' on a Wild Spyware Hunt

I'm not scared,
Got my gun,
My slingshot,
My rubber band,
And my bubble gum.

Uh-oh, do you see what I see?

SPYWARE.
Evil spyware.
Computer-wreckin' spyware.

Can't go over it,
Can't go under it,
Can't go 'round it,
Gotta go through it!

(if you didn't get the above it just means you didn't spend enough time away at summer camp as a kid, so don't worry LOL)

As per the previous post I decided to go spyware hunting to see if I could get rid of those nasty pop-ups that come up with my page, courtesy of my long-time nemesis ValueClick. So far I've run Ad-Aware, Spybot-Search and Destroy, and Ewido (in that order). Each of them came up with about 50 items, which I immediately dispatched, including ValueClick stuff from the latter two programs, but to no avail. I'm absolutely stumped.

Grrr. Back to the digging...
