norton never uninstals easily. it gave me trouble even while unistalling its symantec on my mobile fon.
see if swetanshus link helps u; else try this :
from add-remove programs. try to uninstall its components independently, starting with the main norton.
if u r stuck reinstall norton so that u can uninstal t again properly.
if u want, try to use 'advanced uninstaller pro v7', where it has a 'forced uninstall' option.
if this still fails : remove the folder/files manually. some may refuse to delete. do so, then in the safe mode. or else use 'deletedoctor of
www.diskcleaners.com
then use 'ace utilities' or system mechanic' or 'ccleaner' or 'tune-up utilities' to cleanse your registry of invalid entries. no harm if you use two. visit
www.download.com to get these.
lastly, if u still c the norton entries in ur add-remove program, use 'remove entry' option. most of these utilities have this option !
have fun !
