Samba Processes

Since upgrading I keep getting random samba processes that eat up 30+% of my GPU and cause my laptop temperature to fly into 70s while browsing normal. Killing the process works temporarily until it starts back up again. I don't know why these processes are occurring - as far as I know, Samba is only for 'sharing' between network computers. The printer is not set up with Samba, either.

I want to clarify before I purge Samba to stop these processes that Samba isn't needed for anything essential. (I do not plan on sharing files between network users). I did not have any random samba processes popping up on 15.10, any ideas on that?
