Basic Firewall+Leak Protection= Some leak protection & the Network Firewall.
Basic Firewall= Just Network Firewall.
Firewall & Defense+= Everything, including malware protection.
You can switch between Defense+ & The Firewall after installation. Just disable D+ or leave it on; which is recommended to fight malware and have more control over your apps, including 100% leak protection.
To check that your running Defence+ fully(ie not network security) have a look under Miscellaneous/Manage my Configurations/Select.
There are two options,the one you are using has a tick next to it.For full D+ you need to have “optimum security” ticked and greyed out(may require a re-boot)
In the “Monitor settings” tab all boxes should be ticked.
