It is a normal noise. At low light and high ISO the image will be noisy and there is nothing you can do about it. But you can minimize it by shooting in better light. How do you know if the light is OK? if you set your max ISO at 800 (maybe 1600 is still acceptable) and if the display still looks bright you are probably OK. If it is too dark you can up the max ISO but you will get noise. Shoot couple tests.

Is this zoomed or full frame. In photography this still could be noise from long exposure - "hot pixels". To test if the camera is OK you may put it on tripod and in the photo mode so you can use different shutter speeds. Then try different combination of ISO and shutter speed and see if you can duplicate your posted photo.
