Firewall Rules Erased

Bitdefender 2017 installation erased my security settings without warning.

Particularly the Firewall Rules.

  I had over 100 custom rules for the Firewall.  All gone.  No backup.  These should be carried over automatically.  Otherwise, provide the user a huge warning and option to cancel.

    Now I have to spend the first few hours of my work day, wasted, searching through each and every program to find the ones that need custom rules, and set them up.
