Symantec AntiVirus Instructions for Mac OS X

Download the Installer

Go to our Downloads page and download the 12.1.4 installer for Mac OS 10.6.8 and later (for Snow Leopard, Lion, Mountain Lion and Mavericks).

If you are working on OS X 10.5 or earlier, download the appropriate installer (listed below the most recent version).

Remove Existing Antivirus Software

Symantec AntiVirus will not work properly if another virus scanner is running at the same time. Make sure you uninstall older versions of Norton or other antivirus software before running this installation.

Run Installer

NAV Disk Image

Find and double-click the installer disk image you downloaded earlier. (Depending on your browser settings, it may have already opened the disk image automatically.) Now, inside the open disk image, double-click the Norton AntiVirus installer icon.

NAV Installer

You should install with all the default settings. Keep clicking Continue at every screen, to read the installation notes, accept the license agreement, choose a destination drive for installation, and finally to begin installation.

When the installer finishes, the last screen will prompt you to logout. Don't click Logout yet! We've got a few more things to do. You may just leave the installer open and ignore it for now.

Run LiveUpdate

Norton QuickMenu

After the installer finishes, it should put a black and yellow yin-yang icon in the top menu bar - this is the Symantec QuickMenu. Click the icon, go to the LiveUpdate menu, and choose Update Everything Now.

This will start LiveUpdate, the program that downloads the newest virus definitions and program updates for Symantec AntiVirus. It will automatically connect and start downloading updates - so make sure you have a network connection first.

When it's finished downloading, it will report all the updates that were installed. Click OK, which will bring up the main LiveUpdate menu.

Finally, schedule future LiveUpdates and virus scans.

Symantec Scheduler

Now we'll schedule a time for Symantec to automatically download updates in the future. Click the Symantec Scheduler button in the LiveUpdate menu. (If you don't see the LiveUpdate menu, click on the yin-yang QuickMenu, and from the LiveUpdate menu choose Open Symantec Scheduler.)

New Schedule Product Update

Symantec Scheduler will open. Click the New... button, then in the next window click Product Update. In the window that appears, give the scheduled task a name like "Weekly Update". Make sure All Products is selected, set the Frequency to Weekly, or Daily for the nervous. Then pick a day of the week and a time for the update to run, when your computer will be on but you probably won't be using it. When you're finished, click Save. (See the screenshot).

While you're here, you can also setup a scheduled virus scan that will periodically scan your hard drive for viruses. In the Symantec Scheduler window click the New... button again, this time choosing AntiVirus Scan. Enter a name and a scheduled time as before, then click the Browse... button to choose which drives should be scanned.

Scan Hard Drive

The interface here is slightly confusing: the drop-down menu at the top of the window shows what is currently being selected. You probably want to scan your whole hard drive, so if it shows the name of your hard drive in the drop-down list, then click the Select button. You may also choose specific sub-folders, like your Home folder, if you so desire. You can add multiple drives to scan by clicking the Browse button again. When you've added all the locations you want scanned automatically, click Save.

Wrapping Up Installation

Now you may go ahead and logout; close all other windows and go back to the installer window, which is still waiting for you to click the Logout button to finish installation. When you logout and log back in, AutoProtect will be turned on, which means that AntiVirus is watching for virus activity in the background.

When you want to run a virus scan on particular files, you can easily open the main AntiVirus program from the QuickMenu. Just choose the Symantec AntiVirus menu, then click Open Norton AntiVirus.
