Since installing a newly-purchased copy of Norton Security, I am getting a message every time I boot. It is the phrase in my title above, with a four-digit number in parentheses. I am given four options for dealing with the "service", one of which is, "Allow all connections to this server". Another is to leave the firewall as it is. My problem: why am I getting these warnings? What might the source ("service") be and is it something to worry about? I don't know which option to choose because I have no idea what sort of service is starting. My only guess is that it may have something to do with Apple's cloud that somehow connects to my computer(s). Any enlightenment would be most welcome. I am running Mac OS X 10.11.
Thanks
