I'm using OS X El Capitan on iMac 21.5". As an experienced user, I follow activity monitor sometimes for security of my device. For 2-3 days,"ss_conn_service" is running on my device. I cannot determine what the process do. I suspect from a Galaxy Tab which I plugged to my device 2-3 days ago. Did you encountered with this process ?
Sample of the process obtained from Activity Monitor:
Analysis of sampling ss_conn_service (pid 62) every 1 millisecond Process: ss_conn_service  Path:
/Library/LaunchAgents/ss_conn_service Load Address: 0x100000000 Identifier: ss_conn_service Version: ??? Code Type:

/Library/LaunchAgentsto see the one that's loading "ss_conn_service" and see what the path to the "ss_conn_service" executable is. This might provide additional information to help determine the source. As to deleting it, if it is for your phone then if you don't plan on connecting your phone to the computer again then deleting it shouldn't hurt.
