Technical Tip: Regular Antivirus, IPS, and Application control Scheduled update not working
Description
This article describes how scheduling updates ensures that the virus, IPS definitions, and application control signatures are downloaded to FortiGate regularly.
In some scenarios, FortiGate is not able to receive regularly scheduled Antivirus, IPS, or application control updates. Only a manual Update that functions.
FortiGuard updates can be scheduled in the GUI under System -> FortiGuard -> FortiGuard Updates.
This article describes how to resolve this issue.
Scope
FortiGate.
Solution
Solution
Updating Antivirus, IPS, or application control definitions can cause a brief disruption in traffic that is currently being scanned while FortiGate applies the new signature database.
Updates should be scheduled during off-peak hours when network usage is at a minimum to ensure that network activity will not be affected by downloading the definitions files.
When all policies on the configuration have no UTM (AV, IPS, or APP) enabled, Regular Scheduled for Antivirus, IPS definitions, and APP signatures will not work even if scheduled updates are configured.
Updates only work if in there is at least one policy with UTM (Antivirus, IPS, or APP) enabled in the configuration.
Enable Antivirus, IPS, or APP in one of the policies, and then, regular schedule updates will start working if it is configured. The current version, last time updated, and last update attempt result using the command 'diagnose autoupdate versions'.
Checking version information and the last time updated in the GUI:
On the web GUI the current version and last time updated can be checked under System -> FortiGuard -> Licence Information.
To check AV Definitions, check under AntiVirus -> AV Definitions and hover the mouse of the version to see the last updated date.
To check IPS Definitions, check under Intrusion Prevention -> IPS Definitions and hover the mouse of the version to see the last updated date.
To check Application Control Signatures, check under Firmware & General Updates -> Application Control Signatures and hover the mouse of the version to see the last updated date.
Checking version information and the last time updated in the CLI:
The current version, last time updated, and last update attempt result using the command 'diagnose autoupdate versions'.
To check AV Definitions:

Note:
- Check that the FortiGate has a valid contract.
- Antivirus/IPS are updated using port 443 while Web filtering/anti-spam are contacted using either port 53 or port 8888.
- Ensure that nothing is blocking traffic from the FortiGate on these ports.
