False Positive Virus PDF

L3 Networker

We are detecting that several PDFs that we share on our internal network are being detected as VIRUS.

As we have the antivirus profile enabled in a security rule the session is reset .

Does anyone know how I can avoid this?

Hi @Alpalo ,


If this is a false positive you should gather the PCAP from the threat log and send it to support for analysis so they can get the signature fixed.  If packet capture isn't enabled then you can enable it in the security profile.


As a workaround you can create an exception until the false positive is fixed:



Hope it helps,

Also if its being detected as one of the 'generic' definitions, then most likely its a false positive. Happens from time to time as the generic definitions are quit broad.
