I installed AVG Ultimate and since then I keep getting an error message when I try to open my camera. The error message I get is 0xA00F4244 - No camera attached. I am running Windows 10. I have tried to uninstall and reinstall the cameras and after uninstalling and rebooting the system the cameras work but not for the facial recognition option. When left overnight the cameras disappear again. Has anyone got a solution for this problem please. I have tried to disable the webcam protection too but no success.
