I can't figure out how to install Home Search Assistant, Search Extender, and Shopping Wizard. There had also been a marquee-like item appearing at the top of my desktop saying "Warning! Your computer is infected! Press here for help!" After running Spyboy S & D, Ewido, and a few other such programs, the marquee banner seems to have been removed. But no matter how many times I run those programs, the HSA, Search Extender, and Shopping Wizard won't go away :-( Here's the hijackthis log: Someone please help!!!
