Migrating your legacy Norton 360 app to the latest version

In most cases, your Norton app updates to the latest version automatically. But if your upgrade didn't happen on its own, you can do it manually using the Norton Upgrade tool.

Your existing subscription and remaining days are carried forward to the new Norton 360 app if you sign in using the same Norton account credentials that contain a valid Norton 360 subscription.

If you have any other questions related to this migration, refer to the FAQ section below.

To help you, here are some frequently asked questions around this migration or the questions you might have after the upgrade:

Why is this migration happening?

To ensure better protection, performance, and future updates, we are announcing the End of Life for several older versions of our Norton 360 app. With the 22.x and previous versions being the older versions, we recommend upgrading to the latest version of the Norton 360 app to receive the latest protection.

What is the supported Windows OS version to install the latest Norton 360 app?

Supported Windows operating systems

  • Microsoft Windows 11/10 (all versions except Windows 11/10 in S mode)

  • Microsoft Windows 11 with ARM processors, except for mixed reality and IoT editions

  • Microsoft Windows 8/8.1 (all versions)

    Some protection features are not available in Windows 8 Start screen browsers.

  • Microsoft Windows 7 (32-bit and 64-bit) with Service Pack 1 (SP 1) with SHA2 support

Unsupported Windows operating systems

  • Windows XP

  • Windows Vista

  • Windows 7 (Service Pack 0)

To find your Windows OS version, refer to the following article: Microsoft support >Find Information About Your Windows Device.

How do I know if I am using the older version of the Norton 360 app?

Follow the steps below to know the version of the Norton 360 app installed on your computer:

  1. Open your Norton device security app.

    If you see the My Norton window, next to Device Security, click Open.

  2. In the Norton app main window, click Help.

  3. In the Help Center window, under General Information, click About.

If your Norton 360 app version is 22.x or earlier, and if your device is running on a supported Windows operating system, then you must upgrade your Norton 360 app to the latest version.

What happens to my backup and settings after migrating to the latest Norton 360 app?

  • Ensure that you back up your existing Norton Cloud Backup data.

  • If your Norton app version is 22.21.6.53 and earlier, you may need to reconfigure the core protection features (real-time protection, scans, etc.) after migration, but protection coverage is maintained or improved as part of the migration initiative.

What happens to my existing subscription after migration?

Your existing subscription and remaining days are carried forward to the new Norton 360 app if you use the same Norton account and an eligible plan.

What are the key differences between the legacy and the new Norton 360?

New features:

  • Sandbox: lets you open suspicious apps and files in a secure environment (Windows only).

  • Quarantine: a secure environment for suspicious files and viruses that won’t allow them to infect your device (Windows only).

  • Sensitive Data Scan: part of Cloud Backup, it works in the background to identify sensitive data on your device that you might want to store in the cloud (Windows only).

  • Startup Manager: helps get your Mac started faster by enabling you to select which applications launch automatically when your Mac is turned on (Mac only).

Updated features:

  • SafeCam: in Norton 360 plans we’ve added protection for your microphone in addition to your webcam (Windows only).

  • Ransomware Protection (formerly Data Protection): this feature has been renamed to make it more intuitive and easier to find.

  • Email Protection: this feature now works for any email client, not just Outlook. We have removed the AntiSpam functionality because we weren’t able to provide the correct level of user experience we wanted. This only applies to the spam filter itself. The rest of the email security features have been retained in Email Protection (Windows only).
