ClamAV triggering Windows Virus & Threat Protection
-
Windows Server 2022: I'm seeing the following in the Security/Antivirus log:
* INLINE SCANNING ERROR: ClamAV error while scanning file c:\mdaemon\queues\temp\md5001000000064.wrk!
At the same time, Windows Virus & Threat Protection reports:
Detected: Trojan:Script/Sabsik.TE.A!ml
Status: Severe
Details: This program is dangerous and executes commands from an attackerAffected items:
containerfile: C:\MDaemon\Queues\Temp\md5001000000064.wrkI assume this is a false positive? Is so, what's the best way to stop it triggering??
Thanks,
Cameron

We recommend excluding any first party (Win Defender) or third party antivirus solutions from scanning and/or monitoring the C:\MDaemon directory and sub-folders to avoid any interruptions in mail flow.

In this case it appears Windows defender detected a trojan while ClamAV was trying to scan the message through its own definition database.

It happens so often that it seems Windows Defender believes the MDaemon .wrk files are the trojan!
I've excluded C:\MDaemon from scanning so hopefully that will do it.
