Firewall

Hello,


I use Bitdefender Total Security 2015 under Windows 7, and I note that the "advanced" tab configuration of the firewall has disappeared. This is not the first time this has happened. Each time I must resume my notes and redefine advanced options for each of the programs.


Questions:


1 - why the configuration of the Firewall disappears?


2 - Is there a possibility to maintain the configuration of the Firewall in order to reinstall it in the event of loss of configuration?


Thanks for your help. Juanma
