Two days ago, Bitdefender started spawning dozens of BDExtensionCommunication processes, which consumed 99% of the CPU. (I'm presuming there was an update). I killed them, and the cpu returned to normal. But they came back. A reboot did no good. A removal and reinstall did no good. Disabling Bitdefender did no good. So I've had to delete the application to make my Mac usable. Which is clearly not a good solution. Does anyone have any ideas?
