So I'm new and I'm using Cycles rendering.
The problem is that when I render I get white particles all over the image.
I learned that MIS helps out with that, but I don't know how to apply it as I am using Emission on material.(I am not using any lamps and I know that they have this option)My blender view
currently using 2.79 as I find it easier to navigate.
Is it possible to fix it with nodes? or at least someway else.

1Not that the proposed duplicate answers do not address the real problem: fireflies. More samples won't necessarily clear fireflies. – no-can-do Oct 02 '20 at 15:12

In the Properties window, Rendering tab, Sampling panel, you'll find the Clamp options. Try to change the Clamp Direct to 1 or to play with it a little bit.
EDIT: I just noticed there is a bulb (glass material). Maybe you'll have to play with the Clamp Indirect too.
Explanation of what happens: These white pixels are called "lucky rays". It happens in Cycles when you have many reflections. They are light rays that arrive to the camera in less bounces than the others, so their light is more powerful. Playing with the clamp values you clamp the light to a value, so this rays are not so powerful anymore.

2A common term used to describe those bright pixels in rendering is "fireflies". – no-can-do Oct 02 '20 at 15:13
