AltaVista has been a mess lately... their search results are very unpredictable. I would email them and tell them your site's URLs have changed. If you're really lucky, someone may be able to manually update your listings and remove the old URLs.

However, if AltaVista is your only major concern, you would probably be better off just waiting for their database to become stable again before you try contacting them about it. It may fix itself.
