If you are using Endpoint Protection you could deploy a script like so. If not, try checking
/Library for stuff relating to BD.
I would also create a smart group or logic in the script to make sure it's only executing on machines that actually have these files present.
Aditionally, if you have your BD install in a package in the JSS and index it, you can create a policy to uninstall it as well.
#!/bin/bash cd /Library/BitDefender/AVP/Uninstaller/EndpointSecurityForMacUninstaller.app/Contents/MacOS ./EndpointSecurityforMacUninstaller
