Uninstalling Norton 2004

[ThaSaltCracka]

My parents computer is currently [censored], because they let their Norton Subscription expire. This is causing a multitude of problems because their Anti Virus also connects to Norton Internet Security. Right now, I think the solution is to just uninstall everything, however I am currently unable to. The standard add/remove program is not working. The computer tells me that in order to unistall this program, I have to be logged into the Norton software. I am also unable to do this, most likely because the subscription has expired. What are my options here. Nortons CS sucks, in fact it might be the worst ever. How can I go about uninstalling this?
