The Web's Best Free Downloads No 23 - HijackThis

HijackThis is a simple but extremely useful tool in the right hands: it lists every non-standard startup setting on your system, whether in the Registry or another configuration file, exposing unwanted startup items, browser helpers and even malware. A single click returns settings to their default value, preventing the unwanted software from launching with Windows. Use with care, though, as untutored meddling in the Registry can have dire consequences.
