If you don't use office uninstall it, it's a separate package.

Is it the default app for xml files or something? Check file associations (uninstall should sort this out) I never install office on my htpc (openoffice is plenty)

Here's something that popped up on a search (it intrigued me) http://www.kbalertz.com/kb_933745.aspx Other statements were check wherefile location is, could be adware, or it could have a worm or virus in a macro. Either way, I say disappear it.
