Two small free program U can try:
(1) CWShredder: A small utility for removing CoolWebSearch (aka CoolWwwSearch, YouFindAll, White-Pages.ws and a dozen other names). Spybot S&D and Ad-aware tend to forget essential parts of the hijack, so until they update, you can use this to completely remove the hijack.
(2) HijackThis: A general homepage hijackers detector and remover.
