Situation: Another document in the Symantec knowledge base or a Symantec Technical Support technician sent you here.
Solution: SymNRT is a program that can remove some Norton software from your computer. SymNRT runs on Windows 98, Windows Me, Windows 2000, and Windows XP.
SymNRT should be used only if you have tried to uninstall the Norton program using Windows Add/Remove Programs and that did not work.
