I have a 200F fortigate firewall with fortios 7.6 . Its antivirus did not get update since 2024/08/16. All other modules update without any problem.

Might be because signatures will only be updated if used. If you have an AV profile, have you used it in a policy? If not, you've got an explanation.
If any AV profile is in use, I would check the source IP for Fortiguard service
config system fortiguard
set source-ip x.x.x.x
and insert, like, the LAN IP of the FGT. Try the update again with "exec update-now".
Here are couple of more useful KB articles regarding this issue that may be helpful.

I encountered a wired situation. If you look at the attached screen shot, the AV version on my fortigate is higher than the AV version on fortigaurd . That is why it does not update. When I enable debug it says all up to date.What should i do?
Hi @rezafathi
AV engine version 7.0 0030 is the one which is associated with FortiOS 7.6. That is the last released version:
https://docs.fortinet.com/product/avengine/7.0
https://docs.fortinet.com/document/avengine/7.0.0/build-0030-release-notes/277203/introduction
It is expected behavior that it will not update to a newer version, since there hasn't been any newer version released yet.

Hi
Thank you for your response. what about AI Malware Detection Model, Antivirus Definitions and Mobile Malware? Their last update is 2024/8/16 .
Dear Reza,
The AI Malware Detection Model, Antivirus Definitions, and Mobile Malware systems were last updated on August 16, 2024. Since that update, there have not been any new updates or revisions made to these systems.
You can even check in the support portal to check if there are any updates and if you have any, you can manually download and upload the same on the FortiGate.
Regards,
Chandan
Hi
When I see the antivirus section on fortiguard website, it updates every hour or minute. Before updating my FGT to 7.6 , it was getting update every day.
Hello
The default auto-update schedule for FortiGuard packages is automatic. The update interval is calculated based on the model and percentage of valid subscriptions, within one hour.
