Inbound traffic alert (ESET) - Application: System
I have a MacBook Pro (Retina, 15-inch, Mid 2014) running OS X Yosemite 10.10.2
I have installed ESET Cyber Security Pro a while ago, and an inbound traffic alert just popped up. "A remote computer is attempting to communicate with an application running on this computer. Do you wish to allow this communication?"
The application involved is "System", local port is TCP 8770. The remote computer is fe80::4c8d:97ff:feb4:5d8d, remote port is 56398.
I am still new to Mac, and therefore I'm not sure if I should allow or block. I thought that it might be system updates, but not too sure about that so I'd rather wait for an answer before proceeding.
