searchforit toolbar removal help please!!!

I am running spysweeper, aol spyware, spyware s&d , adaware and spyblaster, however when I run a scan with search & destroy I keep getting a searchforit found report, then when I check with spyblaster it unchecks (unprotects ) it from that program even after I check it.

 

I guess I should have read further down, there already was a thread on this issue. Just a question though, if it is a false positive how come when you back click on the threat and you choose the option to go to it, there is actually a string in the registry that it is calling the threat???
