I often see posters ranting about Norton AV not finding this or that......or issues with not being able to uninstall Norton .........
There are a few things to remember ........
......Norton is intended to protect against Viruses ........
......Norton like any other anti virus ........must be updated regularly to provide maximum protection........
****make sure your auto update is turned on *****
Check it regularly to be sure it is current .......particularly if you don't leave your computer on .
......Norton wasn't designed to catch Trojans ......It will IDENTIFY some ...but not all.
......Removing Norton.......If you wish to remove Norton....
or reinstall Norton ..........(particularly the newer versions which use activation ) ........all traces must be removed or you may have difficulty reinstalling........
After using ADD/REMOVE function to remove ........check your programs folder and be certain the Symantec or Norton folder has been removed........ Then you should remove any remaining bits and pieces by running Norton remover.....http://www.softpedia.com/get/Tweak/Uninstallers/Norton-Removal-Tool.shtml
If you still are having issues reinstalling .........there are probably remaining entries in the registry , which are PREVENTING reinstalling.........Use the registry editor to remove them ...... click START / RUN .....in the run box type regedit  ......then press enter ...when the registry editor opens .......click on the edit tab ........then click FIND...... when the find what box opens .....type in Norton and click find NEXT ...........the registry will be searched ( may take a few seconds ) if there is anything left ....you will be taken directly to that entry( it will be hi-lited....... ( RIGHT click on it and select DELETE )...now go back to the registry editor and repeat the search again .....when you see the message "finished searching the registry" all entries have been removed.
A word of caution ......ALWAYS CREATE A BACKUP of the registry just in case you slip and delete the wrong thing .
Does Norton work as good as other anti viruses .........
I have used AVG , Panda , McAfee and Kaspersky......and I would have to say that it does .
It is definately more of a resource hog than some of the others but it does a excellant job. I use norton on one of my machines and AVG on the other two.....( AVG is free )
Also please remember that Norton or any other Av app doesnt do it all.

This post perhaps should have been in software or other ..but as it pretains directly with viruses ........I posted it here .

Many people have reported problems with Win98. Fewer with XP, but it IS a resource hog? Is it worth it? If you have already paid for it, or it came with the machine you may want to keep it, but as you said, AVG is free. Quote
