The Xupiter toolbar can't be installed on Mac OS 9 or OS X, but it will cause a freeze or delay while the spyware is trying to operate and the various pop-unders and cookies do their dirty work. I'm glad the admins caught this, but I wonder if that wrestling guy switched to the spyware server AFTER the admins had approved his freeware item on a legit server. If so, that is very devious behavior.
