AV:

Go to Security Profiles > AntiVirus and change the radiobutton below ☑ Detect Connections to Botnet C&C Servers from Monitor to Block, hit Apply

Application Control:

Go to Security Profiles > Application Control, click the Botnet Category and select Block, hit Apply

Make sure that the Security Profile is active on your internal to wan policy. Either one should work.

Either one should work.

Actually, the two work on different aspects of botnets.

The botnet C&C IP address blacklist is distributed and updated via the AV engine. This is a simple but effective address filter with near to no impact on CPU.

The AppCtrl signature checks for botnet activity which is not necessarily traffic to the C&C servers.

As such, CPU or CP load is a bit higher.

Both methods should be used at any installation as they complement each other.
