Did a search for you in SARC, there are various worms by the name of goldfish. One worm the W32.Yaha.E@mm will use the word "goldfish" to make attachments. For this worm, symantec has made available a removal tool. (see the link below and do a search for "goldfish").
For the more generic Goldfish worms (A to E), the newest virus definitions should remove it. I'd suggest reinstalling norton (if possible) and update the virus def. If for some reason you cannot access the norton site, let me know and I can email it to you.
