The fastest way to remove Norton 360

The cleanest removal uses Norton's own uninstall tool, which removes the program files and most of its leftover settings in one step. On Windows, go to Settings > Apps > Apps & features, find Norton 360 in the list, click it, then click Uninstall. On Mac, open Applications, drag Norton 360 to the Trash, then empty the Trash. Both methods work, but Norton often leaves behind some background files that can slow your computer or interfere with other security software.

If you want those leftover files gone too — which matters if you're switching to a different antivirus program — you'll need to run Norton's removal tool after the standard uninstall. This tool is called the Norton Remove and Reinstall tool, and it cleans out the files that the regular uninstall leaves behind.

Key Takeaways

  • The standard uninstall through Settings removes Norton 360 but leaves behind some background files that can interfere with other security software.
  • Norton's Remove and Reinstall tool performs a deeper cleanup and should be run after the standard uninstall if you're switching antivirus programs.
  • On Windows, restart your computer in Safe Mode before running the removal tool to prevent Norton processes from blocking the cleanup.
  • After uninstalling, check your Windows Defender or Mac built-in security to make sure it's turned back on before installing a different antivirus.

Using the standard uninstall on Windows

Open Settings by pressing the Windows key and typing "Settings", then click the Settings app. Go to Apps in the left sidebar, then Apps & features. Scroll down until you see Norton 360 (it may also appear as "Norton LifeLock" or "Norton Utilities"). Click on it once to highlight it, then click the Uninstall button that appears.

A window will pop up asking you to confirm. Click Uninstall again. The program will remove itself, and you may be asked to restart your computer. Do restart — this clears Norton processes from memory so the removal tool can work properly later if you need it.

Using the standard uninstall on Mac

Open Finder and click Applications in the sidebar. Look for Norton 360 (or Norton LifeLock) in the list. Right-click on it and select Move to Trash, or drag it directly to the Trash icon in your Dock. Then click the Trash icon, right-click inside, and select Empty Trash.

On Mac, the standard uninstall is usually more complete than on Windows, but Norton may still leave some preference files behind. If you want those removed too, you can search your Library folder for any remaining Norton files, but this is optional and not necessary for most users.

Running Norton's deeper removal tool on Windows

If you're switching to a different antivirus program, run Norton's Remove and Reinstall tool after the standard uninstall. read it from Norton's support website by searching "Norton Remove and Reinstall tool". The file is called NortonRemovalTool.exe.

Before you run it, restart your computer in Safe Mode. Press the Windows key, type "msconfig", and open the System Configuration app. Click the Boot tab, check the box next to "Safe boot", select "Minimal", then click OK and restart. Your computer will start in Safe Mode, where Norton's background processes won't be running.

Once in Safe Mode, double-click NortonRemovalTool.exe. The tool will scan for Norton files and remove them. This takes a few minutes. When it finishes, restart your computer normally. The removal tool will have cleaned out files that the standard uninstall missed.

Running Norton's deeper removal tool on Mac

Mac users can also read the Norton Remove and Reinstall tool from Norton's support website. read the Mac version, then double-click the installer. The tool will ask for your password — enter it and let the tool run. It will scan for and remove Norton files that the standard uninstall left behind.

Unlike Windows, you don't need to restart in Safe Mode on Mac. The tool can work while your system is running normally. After it finishes, restart your computer to complete the removal.

Checking that your built-in security is active

After Norton is gone, your computer's built-in security should turn itself back on. On Windows, open Settings > Privacy & security > Windows Security and click "Virus & threat protection". You should see a green checkmark next to "Virus & threat protection" and "Real-time protection". If you see a warning, click "Manage settings" and turn on Real-time protection.

On Mac, your built-in protection (XProtect) runs automatically in the background and cannot be turned off. You don't need to do anything. If you're installing a different antivirus program, it will work alongside XProtect.

What to do if Norton won't uninstall

Sometimes Norton locks itself to prevent removal. If the standard uninstall doesn't work, restart your computer and try again — Norton may have been running in the background. If it still won't uninstall, try the removal tool even without the standard uninstall first. The removal tool is more forceful and can remove Norton even when the regular uninstall fails.

If the removal tool also fails, restart in Safe Mode and try the removal tool again. Safe Mode prevents Norton from protecting itself. If you still have trouble, contact Norton support directly — they can provide a specialized removal file for your situation, though this is rare.

Frequently Asked Questions

Will uninstalling Norton leave my computer unprotected?

No. Windows Defender (on Windows) and XProtect (on Mac) will turn back on automatically once Norton is removed. Your computer will have built-in protection while you decide what to install next. Built-in protection is adequate for most users, though some people prefer third-party antivirus software for additional features.

Do I need to use the removal tool, or is the standard uninstall enough?

The standard uninstall is enough if you're just removing Norton and keeping your computer as is. Use the removal tool only if you're switching to a different antivirus program, because leftover Norton files can conflict with other security software. If you're not sure, running the removal tool doesn't hurt.

Can I uninstall Norton if my subscription is expired?

Yes. Uninstalling Norton does not depend on your subscription status. You can uninstall it whether your subscription is active, expired, or was never purchased. The program will remove itself the same way either way.

What if I see Norton files still on my computer after uninstalling?

Some Norton files are normal — they're usually preference files or cache that don't affect performance. If you want them completely gone, run the removal tool. If you see Norton processes still running in Task Manager (Windows) or Activity Monitor (Mac) after uninstalling, restart your computer. Processes should not persist after a restart.

Is it safe to delete Norton files manually from my hard drive?

It's not recommended. The removal tool knows which files are safe to delete and which ones other programs depend on. Deleting files manually can accidentally remove something your computer needs. Always use the standard uninstall or the removal tool instead.
