Just a thought - but do you have the updates loaded for hijack this and adaware?
Might also try cwshredder and then run hijackthis - but make sure you have the most updated version - there are some new adware programs that update themselves automatically with a fix for the updates for spybot and adaware that have just come out.
http://www.spywareinfo.com/~merijn/files/cwshredder.zip - if you get a virus warning when you d/l it for w32/generic.worm or something like that - D/L this version
http://www.spywareinfo.com/~merijn/f...shredder_u.zip - some virus programs see the fix file as a virus
If your computer is too infected, it might not let you to get to those pages - use this instead

If you cant get the cws or hijackthis to run properly - this will help:

http://209.133.47.12/~merijn/files/HijackThis.exe is the link for the newest hijackthis
Also one other thing that Ive found - if you run adaware then run these other programs, go back and run adaware again - it misses some the first time around if they are not exposed
