I would also reboot your system, this just happened to me but I was connected to so many things at once, and running so many tabs it may have been an attack attempt, as the moment I rebooted this did not happen again (at least so far).

EDIT: Nope, it's starting again after a reboot and I'm only doing medium levels of things, a lil concerning..
