I downloaded and installed the trialware of Norton AntiVirus 9.0. It made my PB Ti 15,5" 867 MHz running 10.3.3 crash every time I used it. You know, like when the screen fades to grey and you get that omnius apple message "your computer needs to restart". I tried uninstalling it but to no avail. The uninstaller that comes with the demo gives an error message. Seems it can't manage uninstalling the Norton Autoprotect, which automatically logs on when I log on. It doesnt show up in the startup objects menu in the system preferences so i don't know how to manually remove it. Anybody got an Idea how to rid oneself of this crappy demo?
