Hi,
Recently, I installed BitDefender Antivirus Free Edition to give it a try; and unfortunately it immediately blocked all my softwares and apps from accessing the internet excluding Google Chrome, Windows Mail and Windows Store after a system restart. I tried uninstalling BitDefender Antivirus Free Edition but it didn't resolve the issue. I tried installing the trial version of BitDefender Total Security which had firewall options that might help fix the problem, but the installation was also blocked from downloading the necessary components for BitDefender Total Security. I don't have the option to do a system restore as the recent restore points have gotten deleted. According to some suggestions, BitDefender Antivirus Free seems to be blocking TCP requests from all but 3 softwares. I have included a few screenshots for further information.
Operating System: Windows 10 Home version 1608 (Build 14393.1066)
