The only time I had problems getting rid of progies left behind, it was either a virus that was multiplying or the alienguise suite. If you go into your programs (from your start menu), under Norton, there should be an uninstall link that will remove it. Besides that, if your ad/remove programs do not work, I would go onto their site like Redbuzzard mentioned and find something there. This last time I uninstalled via their "uninstall" link.
