Installing antivirus software is a requirement for use of the University's data network. We provide free antivirus products for students and staff to protect your devices.

The antivirus software that we provide to University staff and students has been rebranded from 'McAfee' to 'Trellix'. If you have the software installed on your devices, you may notice a change in the name and logo the next time the software is updated.

Download free software


Download and install antivirus software for your operating system:



If you have any queries, contact the Service Desk.


Check with your local IT support staff to find out which antivirus solution is in use in your institution.

If you have a self-managed Mac or PC, you can download and install the antivirus software we provide using the links above. If your computer is managed by UIS, it will come with antivirus software installed. Updates should install automatically, but please follow the steps below to confirm you have the up-to-date software version and contact your local IT support or the service desk if it is not up-to-date. 


Keeping your software updated 

Trellix automatically updates its detection files every day which means it should detect any new viruses. You can also check that you have the latest version of the antivirus software.


Scanning for viruses 

The antivirus software is continuously scanning your machine for viruses. It also scans all the files you download. You don’t need to take any further action to ensure your machine is protected. 

Run an on-demand scan if you’re concerned about your machine 

You can run an on-demand scan if you’re concerned that your machine might have a virus. For example, if it’s suddenly running very slowly. An on-demand scan can check every part of your machine for signs of a virus. 

  1. Open the Trellix Endpoint Security application:
    • Windows users: search the ‘Start’ menu for Trellix Endpoint Security.
    • Mac OS X users: from ‘Launchpad’ menu, open the McAfee Endpoint Security (the software is currently still called McAfee on macOS). Alternatively, you can search for it in ‘Finder’.
  2. Click ‘Scan System’.
  3. If you’re a Windows user, you can select the type of scan you want to run: 
    • A ‘Full Scan’ performs a thorough check of all areas of your system. This is recommended if you suspect your computer is infected.
    • A ‘Quick Scan’ runs a quick check of the areas of your system most vulnerable to infection. 
  4. If any threats are found, choose whether to clean or delete the infected file and then close the scan.



Further information for IT staff

UIS offers a Managed Endpoint Protection Service, which helps you to protect your institution's endpoints while giving you an overview of your systems and what's happening to them.
