How To Uninstall Norton Firewall

1. The standard and easiest way to uninstall Norton Firewall:

First, we need to make sure the app isn't running, so lets open Force Quit (from the Apple menu on the top left of your screen) and terminate the app if you see it running:


 - Now, open your Applications folder.
 - Right-click on "Norton Firewall".
 - Click on "Move to Bin" (or "Move to Trash" on older versions of macOS)

2. How to remove Norton Firewall using the Terminal:

 - Open the macOS Terminal from Applications > Utilities.
 - Type killall "Norton Firewall", hit ENTER
 - Type rm -rf "/Applications/Norton Firewall.app", then hit ENTER.
 - If that fails, try typing sudo rm -rf "/Applications/Norton Firewall.app"
 - Now type rm -rf ~/Library/Caches/com.symantec.nortonfirewall, hit ENTER.

This will remove Norton Firewall from your Mac, but some supporting and related files will be left behind. Read on for the best way on how to remove those.
