Revo Uninstaller helps you to remove any unwanted application installed on your computer. I carry REVO around because not everything removes smoothly using the Add/Remove (XP) – Programs/Features in Windows 7. (Used it to remove pesky printer software, outdated antivirus apps, locked applications, etc)
There is the Pro, Free and Portable edition available. (I carry the Portable) and you know how we like FREE!
