is from Patchou, the author of Messenger Plus!. It clearly states how to uninstall the sponsor and then install plus! again without it. The sponsor is completely optional.
And about wipedrive.exe - I think you'll find you agreed to install it, so I don't really know what your moaning about. Just follow the above instructions please. As for posting on codeguru etc, there really is no need, I again will say installing the sponsor is completely optional.
