The DT driver is still running Ducky, so I would suggest manual removal if Daemon Tools doesn't appear under Control Panel > Uninstall a Program (the same driver is also used by Alchohol 120%). In order to manually disable the driver, download autoruns. Open up the package and double click on autoruns.exe. Click on the Drivers tab, scroll down to sptd, and take the tick out of the box next to it. Restart the PC and see how you go.
