Re: No Antivirus logs
I have recently had the same issue and bumped with this forum while trying to find an answer. Finally, I found that:
1) FortiClient (not FortiGate) Web filter was detecting this first, so it never reached the FortiGate
2) Once I disabled FortiClient Web filter, Fortigate detected this virus through web filter, so no antivirus logs were generated, only Web filter
Once I disabled both FortiClient Web filter, and the filter in the policy of the FortiGate, I was able to see the logs for eicar in the antivirus logs.
