Trellix Antivirus Program

Trellix Endpoint Security is provided by Marist College to all students free of charge and updates automatically every day.  It is required that students have either Trellix Endpoint Security or another up-to-date antivirus client installed on their computer. 

Many new computers have a pre-installed "free" antivirus trial. Generally this will last from 1 to 3 months. After this trial period, you are no longer protected against any new threats. In order to stay protected, you would have to pay up to $99/year. Marist has purchased licenses for all students to use Trellix Endpoint Security. Once installed, Trellix Endpoint Security will keep itself up-to-date by updating its virus definition files every day. This ensures that each machine has the latest protection against viruses, spyware, adware, and other malware. Trellix Endpoint Security will never expire, and you will never have to pay to keep it up-to-date while you attend Marist College.

Before installing Trellix Endpoint Security, please make sure that you have removed any other antivirus software from your system. The installer can be downloaded after signing into myMarist at, and installation instructions can be found on our How-Tos page.

Please note that the download link above is not accessible to incoming students until August.


Note About macOS 13 Ventura

As of 11/8/2022, Trellix Endpoint Security is not currently supported on macOS Ventura. For further details, refer to "Critical known issues" on this page: However, if you have already upgraded to macOS Ventura, please follow these steps to fix the "Your Mac is at Risk" message:

  1. Go to the window referred to in step 9 (page 6) in our Trellix install guide for macOS - open System Preferences, click on Security & Privacy, then scroll down in the left sidebar to "Full Disk Access".
  2. Select the three Trellix executables granted full disk access (fmpd, VShieldScanManager, and VShieldScanner) one by one, click the minus icon near the bottom-right corner of the window to remove them from the list, then restart your computer.
  3. Go back to the same part of System Preferences mentioned above and re-enable full disk access for the previously removed executables by following steps 9-11 (pages 6-7) in our Trellix install guide for macOS. Please note that macOS Ventura no longer has the lock icon in the bottom-left of System Preferences, it will simply prompt for Touch ID or password when authorization is needed for a settings change.

After these steps are followed, Trellix should re-enable threat protection features on its own after some time. If it isn't re-enabled within a few hours, please contact the Help Desk at
