Yes, guaranteed fully secured. The securities of our wallet can't be base of what we've using, it only depend the holders how they handled on it. Since we are in online system, still we are all vulnerable for hacks and possible of losing our keys somewhere else. With that scenarios, careful and back-up of our keys are very important, and even using other pc isn't advisable cause it only lead others to know your transactions and even your account keys.
