I checked my activity monitor to try and find out why my macbook was always whirring even when I wasn't doing very much. I found that there is a process going called 'nortonautoprotect' with the user 'root'. I don't have norton antivirus (I used to but uninstalled it) and every time I try to quit this process (it takes up an enormous chunk of what the computer is doing) it just starts itself up again after a little while. Is there any way I can stop this from happening? I don't know if I have explained this very well - I don't have much knowledge of computers. Thanks.
