Hello everyone.

I have a Mac pro 3.1 running OS X 10.11 El Capitan. At the root level of my hard drive there is a folder called (Null). Inside is a folder called WiFiAgent, and inside that is a whole bunch of files called WiFiAgent with different date stamps. I have deleted this folder a few times, but then it always recreates itself, so to speak.

Does anyone know what this is ? Should I be worried.

Thank you.
