Any suggestions eg software that would pick it up
I'm loathed to recommend anything specific as I hate all anti-virus/anti-malware software almost as much as virus/malware themselves , so maybe see here for suggestions.
Have you isolated the the device as I suggested here?
If the infected device is a PC, then you might want to use the Windows Resource Monitor (Network tab) and see if you can notice unusual processes.
