Why do i get this in my render?

why do i get this in my render. in the first scene my areas where there is low light, where the arrow is pointing. i get weird colors in this area. how do i prevent this?
in this scene why do i get white dots or noises or whatever it is on my renders?
i usually get this when the light source reflecting on that material is the sun.material v-ray setting on reflection layer:
highlight glossiness - 0.65
reflection glossiness - 0.75

can you post perhaps a higher resolution detail? I can't see any white dots in your low-res images.
I am guessing though that you could increase your "subdivs" in your reflection settings if you need a cleaner looking semi-glossy reflection. Use something like 16 or 32 instead of the default 8 (the higher the number, the longer the render will take)
You also look to have some dark shadows in the corners next to the cabinets in that first image. It may be useful to increase your GI lighting or add some area lights shining from behind your viewpoint to decrese the contrast. -
It's occured with me to. Some white dots in material with reflection on the sun. Look at the black clambing in the window.

This is noise associated with low subdivs. I would suggest to up your Subdivs multiplier in the DMC sampler options. Try 1.7 or 2 - This will apply a X2 to all subdivs in the model - not just materials but light subdivs and GI as well. Also change your noise threshold to .003
Render times will increase dramatically, but your renderings will be much cleaner. The noise on glossy reflections is the sacrifice we make for faster render times sometimes.

I understood. Many thanks valerostudio, I'll try this.
