Mad!!! Ok most of these will seem like stupid questions but I'm working with a minmal knowledge of Frontpage, Dreamweaver I could help much more since were not using dreamweaver thats out of the question. Alright here we go.
Not Found
The requested URL /_derived/nortbots.htm was not found on this server
1) Have you specified the server?
2) Have you tried to debug the script and find out where the evil code is coming from?
3) Are you sure you loaded the files into the server before you tried to view them?
4) Are you sure the url your trying to access is what your site when you try to preview it is trying to find?
*) Microsoft FrontPage is famous for adding script that is not necceray and can make the coding off. If you had access to any versions of dreamweaver it can go through your coding html java you name it and debug it. Its a wonderful tool I come to use more and more through out the day.
Other than these few questions I do not know which way to point you. Other than tward' a nice bottle of scotch.
