How to disable touchscreen PERMANENTLY

[ENSTRAND]

Just this week my two year old Envy started suffering "ghost touches" (?) at the lower left hand corner of the screen. I ran the HP hardware check on the screen and apparently it is just suddenly damaged. I need a way to permanently disable or destroy the touchscreen function on this machine and none of my searching has yielded results. This issue prevents me from logging into my machine, at times as I cannot keep the cursor in the password field long enough.

I tried disabling the human interface touch screen, but the system starts it again in the morning. I uninstalled the touch screen interface drive, however anytime the machine reboots it reinstalls automatically and the ghosting in the lower left corner starts again. 

Help?
