ViewpointKiller does exactly what it's name says: Kills Viewpoint Media Player, Viewpoint Manager, and Viewpoint Toolbar.
Viewpoint is an "annoyware"/adware that can display popups on your desktop. It comes silently with an install of AIM and other programs, and can be reinstalled by AIM if uninstalled. It is sometimes very difficult to remove the Viewpoint variants manually or via Add/Remove Programs.
ViewpointKiller attemps to make this process easier. ViewpointKiller removes any or all of the Viewpoint variants once and for all.
