First of all, I've never had Norton, but I've heard it's a pain to remove it.
First thing I would do is browse the Add/Remove Programs through the Control Panel and remove every single piece of software related to Norton / Symantec; if you haven't done so already. This should remove it completely, but since we are aware of some users having problems with the removal of Norton, if you encounter any come back to us and we'll guide you
