Trying to install SEP 12.14

I'm trying to install SEP on an end user's machine and they keep getting the error "Incompatible Norton product (Norton Antivirus) has been detected.  Kindly uninstall Norton Antivirus before installing Symantec Endpoint Protection for Mac".  When I look at the users machine, they do not have any Norton products installed.  The user does have a file with Norton in the name, however, this is not an execudible file.  

Any help would be appreciated.
