I do not understand?

after being on a website, he attempts to launch norton internet security 2002
It should be on BEFORE he goes to a website?....I am not surprised that it is confused

Boot up normally, go into Norton and change the settings there?
then reboot to be sure that they are saved.

Make sure that it is up to date, and that you have the latest autoupdate program.

If you boot into safe mode you should be able to uninstall.

You will have to be logged in as administrator

Cheers
