What shader should I use to remove bright pixels?

In dark areas there're white pixels from normal mapping. I've disabled all shaders, including antialiasing for these screenshots. MSAA helps a little bit with it but that's not nearly enough. FXAA with heavy sub-pixel antialiasing helps a lot but obviously also blurs image. So is there a shader that can be used as best solution?
