Removing Symantec Endpoint Protection from Windows

Because of recent critical security vulnerabilities in Symantec anti-virus products, and CMU phasing out support for Symantec Endpoint protection, we recommend uninstalling SEP and replacing it with the Microsoft anti-malware product available for your Windows operating system. Instructions for Windows 7 and 10 are provided below.

Windows 7

  1. Ensure that Tamper Protection for SEP is turned off. Left click on the SEP icon in the task bar and open the application. In the main window, click "Change Settings ". Beside "Client Management" click "Configure Settings" On the Tamper Protection tab, uncheck "Protect Symantec Security from being tampered with or shut down". Then click "OK".
  2. If your Control Panel is set to Category View, locate "Programs > Uninstall a program", If your Control Panel is set to Large or Small Icon View, locate the "Programs and Features" button.
  3. In the list of installed applications, locate Symantec Endpoint Protection Highlight the application in the list, and click the Uninstall button near the top of the window.
  4. Confirm you want to remove the application.
  5. Follow the prompts until the application removal process is finished and Symantec Endpoint Protection is no longer in your installed programs list.
  6. If for some reason the application is unable to be removed, please contact the SCS Help Desk for assistance.
  7. Once SEP has been removed, we recommend installing Microsoft's Security Essentials, available from
       https://www.microsoft.com/en-us/download/details.aspx?id=5201.
    Follow the instructions on the above page. When choosing which version to use, you should select the "AMD64" (64-bit) version, unless your PC is very old. Download and run the installer. This will install Security Essentials, and then perform a definition update and quick scan of your system.

Windows 10

If you have a Windows 10 device that SCS has built for you, SEP was not installed, and Windows Defender is already enabled and updating. No changes will need to be made to your system.

If you are a Windows 10 user that has brought your own device and installed SEP on it from CMU Computing Services or SCS, follow the steps below to remove SEP

  2. Right Click the start menu and select "Programs and Features" from the list.
