Third and first person controllers moving on their own

Sorry for the vague title, but this has me really confused. I just installed Unity 5.

When I import the third or first person controller prefab, the character acts as if I’m holding the buttons to move forward and left. This is also an issue with the sample project, in which the car accelerates and drives to the left without any user input. Is my installation broken? Is there a setting I’m missing?

Nothing is broke for me or not in any bug that has be loved. It might be your computer’s keyboard.

Turned out it was a virtual joystick program running in the background, not an issue with unity itself!
