I uninstalled an application using AppZapper called PdaNet. It is a tethering application for my phone.
Now every time I login, I am asked if I would like to allow inboud connections from PdaNet by the firewall.
A search for PdaNet with spotlight does not return any results.
PdaNet creates its own Ethernet in network preferences. This hung around after uninstall. I deleted it but it did not make a difference.
