How to Uninstall Norton Completely: A Comprehensive How-To Guide

Norton Antivirus is a widely used security program designed to protect your computer from viruses, malware, and online threats. However, some users choose to uninstall it for various reasons, such as switching to another antivirus solution, experiencing performance slowdowns, or dealing with an expired subscription. In some cases, leftover files can also cause conflicts with new software. That’s why it’s important to remove it properly. In this guide, we’ll show you how to uninstall Norton completely and ensure no traces are left behind.

Before jumping straight into the removal process, it’s important to understand that uninstalling Norton is not easy cause it is integrated into the Windows operating system, and often leaves behind many residual files that prevent a complete uninstallation. The regular uninstallation method might not be enough, so you’ll need an advanced tool to do a deep uninstallation. But before that, it’s needed to go over what you should know before uninstalling Norton.

• Ensure you have another antivirus installed (for protection)

• Save the product key if you plan to reinstall Norton

• Close all Norton-related processes before uninstalling

How to uninstall Norton completely? Generally speaking, you can uninstall Norton via the Settings, Control Panel, and other regular ways, but sometimes the usual methods alone often aren’t enough, as Norton is known for leaving behind services, drivers, and registry entries. Therefore, you’ll need a more thorough approach, such as using the official Norton Removal tool or a third-party uninstaller - IObit Uninstaller. Each way has its pros and cons, as shown below.

Method 1. Use the Official Norton Removal Tool

Using the official Norton removal tool is one of the most reliable ways to uninstall Norton products from your computer completely. This tool—commonly known as the Norton Remove and Reinstall Tool (NRnR)—is designed to remove all Norton files, leftover registry entries, and hidden components that standard uninstall methods often miss. But one thing to note is that you can’t selectively uninstall one component. Moreover, using this tool will also delete saved preferences and configurations. If you don’t mind, here’s how to uninstall Norton completely.

Step 1. Download the Norton Remove and Reinstall tool from the official site to your computer.

Step 2. Open the tool and accept the license agreement.

Step 3. Click Advanced Options and select “Remove Only” to uninstall Norton without reinstalling it.

Step 4. Click on the Remove button and restart your computer when prompted.

Method 2. Use a Professional Application Uninstaller - IObit Uninstaller

If the official removal tool still leaves behind stubborn files or you want a more flexible, all-in-one solution, turning to a professional uninstaller can make the process much smoother. Tools like IObit Uninstaller are designed to go beyond standard removal methods, scanning for hidden leftovers and ensuring a cleaner, more complete uninstall of Norton and other programs. Let’s take a look at more features of this powerful Norton remover.

If you’re using a Mac, uninstalling Norton completely requires a slightly different approach than on Windows. Simply dragging the app to the Trash isn’t always enough, as some hidden files and background services may remain. To ensure a clean, complete removal, you’ll need to delete the application and its associated system files. Here are the steps.

Step 1. Quit Norton by clicking the Norton icon in the menu bar and selecting Quit.

Step 2. Open Finder > Applications, find Norton, and right-click it to select Move to Trash.

Step 3. In Finder, click Go > Go to Folder, enter the following paths one by one, and delete Norton-related files from the following folders:

~/Library/Caches/

~/Library/Containers/

~/Library/Group Containers/

~/Library/HTTPStorages/

~/Library/Application Support/

~/Library/Application Scripts/

~/Library/Preferences/

~/Library/Cookies/

Step 4. Right-click the Trash icon and select Empty Trash.

Step 5. Restart your Mac to ensure that all background services and cache files are fully cleared.

Even after uninstalling the program, traces of Norton can still linger on your system. These leftover files—such as registry entries, temporary data, and hidden folders—may cause conflicts with new software or take up unnecessary space. To ensure a truly clean removal, the next step is to manually locate and delete any remaining Norton files from your computer.

1. Uninstall the Norton app

Go to Start and open Settings > Apps > Installed apps (or Apps & features), find Norton in the list, click it, and select Uninstall.

2. Delete the remaining Norton folder

Open File Explorer and check these locations, and go to delete any folder named Norton or Symantec:

C:\Program Files\

C:\Program Files (x86)\

C:\ProgramData\ (hidden folder — enable “Show hidden items”)

C:\Users\YourUsername\AppData\Local\

C:\Users\YourUsername\AppData\Roaming\

3. Remove temporary files

Press Windows + R, type %temp%, and press Enter. Delete all files inside the folder.

4. Clean Norton registry entries

Press Windows + R, type regedit, and hit Enter. Navigate to and delete Norton/Symantec keys in:

• HKEY_CURRENT_USER\Software\

• HKEY_LOCAL_MACHINE\SOFTWARE\

• HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\

Use Edit > Find and search “Norton” or “Symantec” to remove remaining entries. Be careful when editing registry entries, as any incorrect changes may affect your system.

5. Check startup items

Press Ctrl + Shift + Esc to launch the Task Manager, then click the Startup (or "Startup apps" in Win 11) tab, and disable any Norton-related entries.

6. Restart your computer

Reboot to ensure all services and remnants are fully cleared.

Even when you follow the correct steps, uninstalling Norton doesn’t always go smoothly. You might run into error messages, incomplete removals, or files that refuse to delete. Understanding these common problems can help you troubleshoot issues quickly and ensure Norton is fully removed without leaving anything behind.
