EPO McAfee VirusScan Update Manually To Latest DAT

Sometimes with McAfee VirusScan you find a client that simply refuses to update. Via the EPO console you can run a client task, update task. But often, this won't work either.

Luckily there is a way to manually update from the client itself. I will say, however, this is usually just a temporary fix. But at least you can get the client up to date there and then and fix the bigger problem later (maybe a firewall issue or even requires a reinstall of the program or even a rebuild of the OS in rare instances).

There is a good article on how to do this on the McAfee site:

How to manually update the DAT files for VirusScan Enterprise 8.x

You basically stop the McAfee services on the client then go to the McAfee support portal and download the zip file for the latest DAT and extract it to "C:\Program Files\Common Files\McAfee\Engine" then restart the services.
