Hey, I had a similar problem on Sunday. In my case, (Running W7), the bad files were coming from Local Settings>Temp folder. My firewall caught them trying to access the internet as 'file loader'.
Basically, loader.exe and smss.exe (not the windows smss) were running in the background as "File Loader". They loaded IE invisibly and loaded ads.
I stopped the process with taskmanager then deleted the files, but to be safe, I restored a system image from a month ago. I also tried System restore, but I think my AV program was screwing with it, so I decided on the image instead.
This still left me with one problem: IE was still loading every time I booted (invisibly, in the background). So, I made a boot cd with W7, booted to it and ran bootrec.exe /fixmbr. This seemed to resolve the rest of my problems.
Btw, Spybot and avast detected nothing on my machine. This is a new problem. I'm not sure if what I had is the same as what you have, but I figure it might help.
