Installation of Norton Security Deluxe proofed simple and straightforward. The basic installation needs a reboot for completing, nothing special as some other developers have an equal procedure. Make sure to uninstall any other antivirus on your Mac before adding Norton. Two similar programs can produce a lot of problems on your running Mac.
During installation the installer asks for permission to install a helper tool. After reboot, open Norton and make sure to run LiveUpdate.
