VirtualBox can't run anymore because Docker for Windows activates Hyper-V during its installation (with your permission). So you have to disable this feature again. You have to uncheck Hyper-V in Control Panel -> Programs -> Programs and Features -> Turn Windows features on or off. After a reboot, VirtualBox should be able to run again.
