Support for Symantec Endpoint Protection downloaded from the Campus Software Library

You should only install one antivirus program on your computer. Having multiple antivirus programs on one computer can cause conflicts. Always uninstall the antivirus software that came with your computer before installing the University’s Symantec Antivirus.

Installation Instructions:


  1. When you download and install the Symantec Windows clients, you get a Download Insight warning from your existing Symantec installation.
    If you get that error, it's safe to click the "Allow this file" button and continue with the installation.
  2. If you receive any of the following errors when installing on a Mac, use this workaround:
    • Install Failed: Invalid Symantec Endpoint Protection Package
    • The application "Symantec Endpoint Protection Installer" can't be opened.
    • It seems like something went wrong with the installation of the product
    • ... cannot be opened because it is from an unidentified developer ...
      macOS cannot verify that this app is free from malware.
  3. According to Symantec, when installing on MacOS 0.13 and later, you must authorize the Symantec Endpoint Protection kernel extension after installation for Symantec Endpoint Protection to fully function. You are prompted during the client installation to do it if needed. If you do not do it during the client installation, go to System Preferences > Security & Privacy, and click Allow. Neither Symantec Endpoint Protection nor the Mac operating system continue to remind you that you must do this. You only need to authorize the kernel extension once during the life of the computer's operating system. If you uninstall and reinstall the client, you don't need to reauthorize the kernel extension. If you have Symantec Endpoint Protection 14 and then upgrade to macOS 10.13, you don't need to reauthorize the kernel extension. However, if you reinstall the operating system, you need to reauthorize the kernel extension.
