I am trying to uninstall norton internet security but it doesn't appear in add/remove programs. Where might it be hiding?

Have you checked the Norton folder in the start menu ?
There's normally an uninstaller loacted there.

Here's a link to the Norton Uninstall tool:

Norton has a newer removal tool that doesn't give the expired message.

Why the old tool doesn't link you to this new one, I can't guess.
Bad business.
