Hello, our customer who uses Avast Business Antivirus 17.9.2528 database version 180126-2 has encountered a problem with the firewall, the firewall blocks almost all traffic, such as ICMP, SMB, and others that limit the customer's work to most stations. If the packet rules are modified, after the pc restart, the changes are again replaced by the original rules. How to keep the rules permanently. Thank you
