Damaged Toolbar - Ie 6.0

Hello all. I sure hope I am posting in the right forum. Anybody ever heard of a program called "iSearch"? Well it managed to install itself into my IE 6.0 toolbar withOUT my permission (although my anti-virus s/w complained about a TROJAN being found) and I had to scour the registry to remove all remnants of it (as well as toolbar.dll from WINDOWS\system32). Now its gone, but now my toolbar has down-syndrome. When I click on View->Toolbars all the toolbar options are grey-ed out. It wont let me modify my toolbar. Anything I can do to fix that? I'd like to just re-install IE, but I know its difficult. Thanks!

Probably not all it added.
