In depth tool for scanning your computer for Spyware.

HijackThis scans areas of your registry and hard drive and returns a log of items which it detects. As this tool is recommended for advanced users only, we recommend you run a scan and then post your log file on a support forum, where someone will be able to suggest which entries to remove.

A general homepage hijackers detector and remover. Initially based on the article Hijacked!, but expanded with a lot of 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 before deleting anything.
