In cases where a detection is low confidence or in an an archive together with clean contents (and there may be other cases as well where Norton/Symantec believe handling the infection may cause damage), Norton provides only one option and this is “Get Support”. Users are supposed to follow the link, contact support and support will decide whether or not it is safe to remove the infection.
Other than that, users can click on “I believe there are still risks” and launch Power Eraser scan or they can use the Norton Bootable Recovery.
