Solution
1) Log in to the Customer Service & Support web portal at https://support.fortinet.com, and select the 'Download' option, followed by 'FortiGuard Service Updates'.

2) Download the files for AV Definition ("Virus Definition") paying attention to select FortiGate device and the correct OS version and model of the device.

3) The current AV Definition version in a FortiGate unit can be checked from either the Web GUI or via CLI.

WEB GUI:

Go to System > Config > FortiGuard > "ATP Services" (AV Definitions)

For example (updating AV Definition):

Clicking on "OK" will result in the message 'Updated successfully' which means that the AV Definition has been updated successfully:

Verify the AV Definition has been updated by comparing the result with the AV Definition shown in the step number 3.
