how to remove virtual drive that is created by alcohol120%

I installed alcohol120% trail version . Later i added crack to it to make it a full version. Later when i uninstalled it, the software still remains and works properly. I later deleted it because it was not there in my add/remove programs. But i was unable to uninstall the virtual drive it created. I tried going to MyComputer and under Device Manager i tried to uninstall the virtual drive. But when i rebooted my system that virtual drive was still present. How do i remove that virtual drive?Please help.
