We are seeing rogue workstations in the control panel after adding our executable to our screenconnect page. I have removed them but they keep coming back. I would highly suggest you at the very minimum update the software to be able to block these connections by their IP and MAC address. This would keep them from showing up in the control panel. Image if this were an enterprise customer and they pushed the installer out to 2000 endpoints. That would make a mess of my account.
