Does the issue persist after uninstalling Bitdefender? If this confirms the issue, you may reinstall it again and begin to take further troubleshooting steps with your AV configuration (or finding an alternative product if not possible).
Additionally if Bitdefender keeps a log of its activities, it can help to look at what it is doing.
The logs showed that it was detected the file as a generic maleware. Uninstalling fixed it but to be honest I've had no issues and most threats are not virus releated so I'll just stuck to malwarebytes and keep bitdefender off. This isn't the first issue of late. before that I found it to be blocking the steam sites SSL using it's ssl scan. So ya. Issue fixed.
