WRONG. Use the Norton removal tool and remove all the objects required to be removed. It is NOT necessary, and is less effective, to try to use a registry cleaner if you are a newbie to such things and pick the wrong one. A couple are great programs; others not so great, others better for newbies.
WRONG. Norton's footprint is now very small and they even show it in a monitor if you wsh to watch it at work in real time. McAfee I no longer bother checking out but you have obvously not checked anything out about any of the programs you speak of; you are way behind the times and are presenting misinformation on almost everything you mention.
