I had to go through the whole ordeal of logging in under "root" to delete certain files... then it took me FOREVER to find where these System Preferences (listed under "Other") were stored, as they did NOT have the name Norton on the actual file, though of course they did on the icon itself. Of course, they weren't located where all the other icons for System Preferences were.
It's times like this that "The Missing Manual" is indispensible. Speaking of, I wonder how out-of-date my $25 book will be once I install Panther.
