I just installed Bitdefender Internet Security from about 2 hours
I used online installer of bitdefender internet security and through installation it disabled windows defender but left windows 8.1 firewall on
I thought it will be disabled during installation or through first configuration of bitdefender but after installing is finished, the windows 8.1 firewall still running with bitdefender IS firewall together
Is this normal!!!!!!!
should I disable it manually or it's normal for both to run together !!!?
note : Iam using a fresh installation of windows 8.1 (updated to latest update) and bitdefender is second program to install
I updated bitdefender IS and it asked for restart and every thing looks fine with both firewalls running till now
this is picture from Action Center

PLEASE Technical Support advice me and thanks
