Have you tried to block VIBER with layer 7 firewall ?

#1. You can use Layer7 firewall to define sites or process you want to block. In your case VIBER

/ip firewall layer7-protocol add name=“VIBER” regexp=“^.(get|GET).+(viber).$”

#2. Create firewall mangle rule, to catch all connections from IP range you want to block access: (Change interface & address)

/ip firewall mangle add action=mark-connection chain=forward in-interface=<INTERFACE_NAME> new-connection-mark=VIBERc src-address=192.168.5.0/24

#3. Mark all packets from previos rule.

/ip firewall mangle add action=mark-packet chain=forward connection-mark=VIBERc new-packet-mark=VIBERpackets

#4. Drop all packets that contain Layer-7 rule and marked packets.

/ip firewall filter add action=drop chain=forward layer7-protocol=“VIBER” packet-mark=VIBERpackets

#Also only with layer7 you can’t block all viber connections, you can add rule, who looks in URL contents:

/ip firewall filter add action=drop chain=forward content=viber packet-mark=VIBERpackets

#Place both firewall filter rules on top of your firewall list !
