If Symantec Endpoint Protection (SEP) is used as a local AV on the machine where MetaDefender Core resides, it can interfere with the correct functioning of the OPSWAT product.
Please change the following SEP settings to ensure everything is working as expected:
Exclude the folder where MetaDefender Core is installed, from the SEP real-time protection: Add security risk exeption > Folder > C:\Program Files\OPSWAT\
Uncheck “Number of seconds to automatically block an attacker's IP address“ from Network and Host Exploit Mitigation Settings > Firewall
Uncheck “Enable Network Intrusion Prevention" from Network and Host Exploit Mitigation Settings > Intrusion Prevention
If you have followed all of these steps and you are still experiencing issues, please see how to create a support package, login into OPSWAT Portal and open a ticket with us, having the support package attached.
