No, dont edit your registry. Viruses often infect crucial windows files. You could be deleting dependant files.
Norton should give you a name and/or a link to their website with a method of removal. If they didnt link you, type the virus name into google and it should pull up symantecs website with that info.
However, if that page (symantecs removal recommendations) says to delete certain registry keys, it should be okay.
Let us know how it goes.
