Deep Security provides a customized option for Anti-Malware configuration file tagged as possible malware. By default, the action is "ActiveAction". If this option is manually changed to "Quarantine", some common software or system files might be blocked.
In certain scenarios, system files will be quarantined as corrupted file "PACP_CORRUPTPE.STD" without logging an Anti-Malware event.
To avoid any false positive, it is recommended to use the default action, which is "ActiveAction".
This is issue has been fixed in Deep Security 10.3.
