Spyware - WebRebates0.exe & WebRebates1.exe

[Mockery]

Ok, I've been trying to get rid of these two things for a while now. I haven't seen them actually cause any ads to pop-up yet, but they're both constantly in my windows task manager "processes" list. I have the most updated versions of Spybot and AdAware and I ran them after rebooting windows xp into safe mode. All the other spyware on my computer is gone, but I can't seem to get rid of these damned WebRebates0.exe and WebRebates1.exe files from my processes.

Any help would be greatly appreciated.

Thankee. :o
