Thank you Sorin, I did as you said. I removed Comodo Firewall, ran the Bitdefender Repair and now my system is running normal again.
Sorry for double post but could't edit the original post. I found a Bitdefender 2016 installation file. After installing the 2016 version I was getting the exact same behavior I was getting when I was running the 2017 version. Which is strange since Bitdefender has been running fine for over a year. I'll update as I find…
Also worked for me, I am however wondering if it is safe to keep the setting on "Trusted" on a home network connection.
