The antivirus software that we provide to University staff and students has been rebranded from ‘McAfee’ to ‘Trellix’.

McAfee EndPoint Protection has been retired and won’t be receiving updates, so we recommend that all users upgrade to Trellix. The functionality of Trellix is the same as McAfee, and it supports macOS Ventura.

  1. Download the Trellix installation software
  2. Open your ‘Downloads’ folder and double click the downloaded file to open it.
  3. Open the ‘Trellix Endpoint Security’ installer package inside the downloaded file.

  6. Select ‘Continue’ on the ‘What’s new’ screen.
  7. Select ‘Continue’ and then ‘Agree’ on the ‘Software Licence Agreement’ screen.
