Dear @Michael Lyon

If Norton is interfering with other security applications or showing unwanted pop-ups, I recommend using Norton's official removal tool rather than trying to remove the software manually.

You can download the Norton Remove and Reinstall Tool from the official Norton support page:

Norton Remove and Reinstall Tool

Run the tool as an administrator and select Remove Only when prompted. Once the removal is complete, restart the computer.

After restarting, I would also check Settings --› Apps --› Installed apps and search for "Norton". If you have additional Norton products installed, such as Norton VPN or Norton Utilities, remove those as well.

You can then open Windows Security --› Virus & threat protection --› Manage providers and verify that Microsoft Defender Antivirus is active and that Norton is no longer registered as the antivirus provider.

I would avoid manually deleting Norton folders, services, drivers, or registry entries. Antivirus products install components at several levels of Windows, and manually removing individual files can leave behind services or drivers and potentially cause other issues.

If you want to make sure the system is completely clean, you can also check for remaining Norton services, scheduled tasks, drivers, startup entries, and Defender exclusions after the official removal has finished.

    1. Remove Norton from Start > Settings > Apps > Installed apps.
    2. Find each Norton entry, select it, and choose Uninstall.
    3. Restart the PC after each uninstall if prompted.

    Important:

    • Running more than one antivirus or antispyware program at the same time can reduce performance, cause instability, or trigger unexpected restarts.
    • While removing Norton, make sure Microsoft Defender Antivirus is enabled and Windows Firewall is turned on so the PC is not left unprotected.

    If Norton does not uninstall cleanly:

    1. Run the Program Install and Uninstall troubleshooter.
    2. Choose Run or Open after downloading it.
    3. Follow the prompts to remove software that is blocked from uninstalling or only partially removed.

    If the pop-ups are tied to suspicious software or a fake security app:

    1. Open Windows Security and run a scan first.
    2. Remove the app only after threats are cleaned.

    If software remains after normal uninstall:

    • Some security software does not uninstall completely through Windows alone.
    • Use the antivirus publisher’s official removal method from its website or contact that publisher’s support.
    • Avoid manually deleting program folders, because that can leave drivers or services behind.

    If the issue still continues, a last-resort option is Reset this PC with keep your files.
