How can I stop WINWORD from starting up?

This is an interesting situation. Every time a client of ours boots his IBM Laptop, WINWORD is started. You can’t open Word without first using End Task. He is using Win98. I went into msconfig to remove things at startup and nothing works. I also checked everthing in sysedit and even searched around for references in regedit to no avail. In Safe Mode, it still loads. Does anyone have any thoughts on this other than a reinstall?
