Thanks to tips from John Baltutis and Harold-P Norton is not history and no more nag notes. It was time consuming but easy to get rig of most of the Norton junk. The hard part was getting rid of the invisible file in the Trash called Norton FS Index. Since it was invisible. the Finder did not think there was anything in the Trash and the Finder's Empty Trash button was dimmed. It could not be found in the terminal so the rm command would not work. I got lucky by messing around in the Finder's Find results by double-clicking on the "Norton FS Index" invisible file shown to be in the Trash. The Finder came back with a dialog box saying the host application could not be found (already trashed) and ask me if I wanted to try something else. I selected BBEdit and it opened the file. I then used the BBEdit Save As command and let it replace the old Norton file. The Finder then recognized Norton FS Index as a file and it could be trashed. Dick
