Arduino in-built LedLED is not turning off

I have Arduino UNOan Arduino Uno whose LED, which is connected to PIN 13 pin 13, is not turning off and it always stays on, and it annoys me.

Touching any exposed pins turns off the LED after removing my hands from the pins it turns back on slowly.

However it works perfectly with the programs. This program does turn the LED off and it stays that way while the program is running.

void loop() {
  digitalWrite(13, LOW);         
}

When I upload other programs that don't use PIN 13 thanpin 13 then it stays on again. How can I fix this?
