I'm having difficulty with the part of Bitdefender installation that installs a kernel extension. In the Bitdefender main window, I see:
To properly run Bitdefender Antivirus for Mac ... you must manually allow Bitdefender to load on your system.
I follow the instructions:
Go to Security & Privacy and click Allow.
Restart your device to apply this change.
In the "Security & Privacy" settings, I see the message:
System software from developer "Bitdefender SRL" was blocked from loading.
I click the Allow button several times, but nothing seems to happen. I reboot, and see the same message in the main window. I've repeated the process, with the same results.
Bitdefender seems to be scanning in the background, but it appears that the kernel extension that allows real time scanning is not installed.
Any suggestions would be much appreciated!
