The first thing I would check is a template called Book.xlt. It is stored in an XLstart folder. This folder is normally hidden and stored in various locations depending on the users login and operating system. So you will need show hidden files and then do a search to find the XLstart folder. You can open this file (as a template) and then edit it to get rid the extra worksheets/data you don't need or you could delete it entirely. This should fix your problem. Let me know how you go.
