BugOff! From Merijin, creator of HiJackTHis, CWShredder, and more.

"A new app is available for download: BugOff. This disables a few exploits that are commonly used by browser hijackers to install themselves onto your system. In essence, it prevents such hijackers from ever installing, like SpywareBlaster.
There are no patches available from Microsoft for these exploits. Even if your system is fully up to date from WindowsUpdate you are vulnerable! This app should be used by everyone that uses Internet Explorer to browse the web. " You can download it at the link below.
