Installed Bitdefender Antivirus Plus on my Macs. The installer also added Bitdefender VPN, with no option to skip it. Adding software without the customer's consent is not an ideal practice.
Dragging the VPN app to the Trash fails, and even sudo gets "Operation not permitted": its self-protection guards the folder.
What works: open Bitdefender Uninstaller in /Applications/Bitdefender and select only the VPN.
Forum users report it can come back with updates 😬
