Windows 10: Computer starts at night randomly and says too many incorrect password attempts

I woke up this night and saw that my computer was running. I shut it down and when I logged on this morning it said, too many incorrect password attempts, try this phrase. It said to enter something like A1B2C3 and then I could enter my password. I found this in the event manager. Is this a virus or just something trying to update?

If this screen on yours says what this says, try shutting down with the power button to see if it works. The Shutdown click-on should follow suit.
