I have another unremovable virus?

i had posted a query for anti-virus software a couple of days ago when i got a really bad one, it had come from downloading what was supposed to be an activeX for watching a video, my question was answered by some very helpful people who told me that 'superantispyware'(SAS) and/or 'smitfraudfix' was the solution, the combination worked, and all the infected files have been removed save one, but now there is another problem, whenever i search anything in my IE or Firefox google toolbars in the top right, half of the time it return search results for 'sex' i scanned my computer thoroughly using uptodate avast and SAS, and it is clean, i deleted firefox, cleared all temp files, downloaded and installed a newer version from a new setup file, but still the problem persists can you please help me, if the people who helped me earlier have more suggestions, i would appreciate it

I use AVG, Ad-Aware and Spybot Search and Destroy. It is always good to have a mixture of programs because while none are perfect, you can keep your system clean with a few. The ones I use are all free.
