my school provides me w/ norton antivirus for os X. i installed it and the app wouldn't work properly because it couldn't find some resource or another. well, i wanted to get rid of it and it but it installed stuff all over my hard drive. i manually searched for everything that contained norton or symantec in the name, and deleted everything. the only thing that's left is "norton missed tasks". OSX wont let me delete it b/c it is in use. is there any way to kill of this last remnant of the original app?
