I too am unable to uninstall Bitdefender Ant-Virus for Mac. I have ran the uninstaller 8 times with no luck. I run it and nothing happens. This seem like a serious problem with this software as the internet is full of people with this issue. Hopefully someone from tech support will reach out to me to offer a fix for this. I have called support and It has been escalated to the big brains of the company. We will see. If I get a fix I will post a how too. I hope I don't have to factory restore my Mac.
