Is it a w32 virii? If so the only time Symantec Utilities will delete it if its in the .../System32/ folder. If its not and its somewhere else you will need to goto the Symantec web page and find out how to adjust the registry in order to fix it. My advice is to backup your Registry and then edit. Even better advice would be to back up your data and re-format. Those W32's can be a pain in the neck.
