While looking at alternative browserss I did a search query involving the true uninstallation of IE, and I found this little gem. It apparently only removes 3.0 and up(since Avant still works, im using FireFox), but still. Unique in the way that KillTheMessenger is unique, but more useful. It's called IEradicator.
