Well you should probably read the manual.
Anyway, it's not an "annoying" problem, but instead it is there to indicate that the shutter speed will be slow, and therefore shaking and blurring may be in your image. You need to change one or more settings (such as ISO, aperture or shutter speed) to allow a faster shutter speed. This will depend on which mode you are shooting. Alternately, you can opt to use the flash. But your question of "How do I make it go away?" shows that you don't understand it's purpose. It's a warning that you may get a blurred image. This is all explained in your manual. Good luck.
