After installing Hotspot with Revo Uninstaller then uninstalling it completely from my system, I'm still left with Hotspot's VPN adapter driver.

This bothers me a great deal. Unfortunately I did not make a system backup prior to installing Hotspot. Uninstalling it from hardware devices does nothing.
Searching for * hss*.* which is associated with said driver, gives me this result:

How can I uninstall this driver?
