That should have been removed using the clean tool. Any piece left over memory resident is a problem, when your using the clean tool, to diagnose an issue.
There is a special 2014 clean tool to enable a downgrade to Endpoint. I wonder if that leaves it also.
Did you do an un-install prior to the clean tool run in safe mode?
