I have this symantec live update in my add/remove programs. Is this for norton antivirus or something else? I don't use norton antivirus and was wondering if I should remove this from my computer or just leave it alone. Thanks

It is probably for Norton's firewall, antivirus or combined program - but it could be for other Symantec products. Do you have other Symantec products installed that you're using? If not, then nuke it.
