HijackThis (zipped): A general homepage hijackers detector and remover. Initially based on the article Hijacked!, but expanded with almost a dozen other checks against hijacker tricks. It is continually updated to detect and remove new hijacks. It does not target specific programs/URLs, just the methods used by hijackers to force you onto their sites. As a result, false positives are imminent and unless you are sure what you're doing, you should always consult with knowledgable folks (e.g. the  forums)  before deleting anything.
 A rudimentary HijackThis log tutorial by me is available here.
 The official HijackThis QuickStart for posting on the SpywareInfo  forums is available here.
