The back rotor of the helicopter counters the force applied to the body of the helicopter by the main rotor by applying thrust in the same direction as the main rotor. The force from the main rotor is applied in the opposite direction the main rotor is spinning. So say the force the main rotor was exerting on the body of the helicopter was causing the tail to move left then the back rotor would be designed to apply an equal force pushing the tail right to keep it from spinning.
If the back rotor of a helicopter malfunctioned it would begin to spin.

Why doesnt a helicopter Spin out of control?
Most helicopters have a tail rotor for stability while others (often Russian military helicopters) have two main rotors. In both cases the two rotors spin in opposite directions, in order to cancel out any torque effect of a single rotor.
Do helicopters defy gravity?
The rotor blades are designed so that as they spin they push down on the air, which in turn pushes up on the blades, creating lift that acts counter to gravity.
Why don't helicopters spin around in the air?
Some helicopters feature a second rotor underneath the first rotor that counters the force applied to the body of the helicopter by applying thrust in the opposite direction of the main rotor. This stops the helicopter from spinning around. Others, instead of a second rotor underneath the first rotor have a back rotor that essentially does the same thing, which is provide a equal force to the first rotor preventing the helicopter from spinning =0

That is to stabilise the inherent spin of the main rotor and to steer the machine.
