Take a search here about fireflies.
This will be solved soon ( v2.1 or v3 ). Meanwhile you can try a workaround ie. with hotpixel app or what I suggested...
take a look around here

i read that increasing the amount on the roughness setting will help avoid hot pixels also. around 170 or something

hot pixels = white points = white dots = fireflies

Hi,

These are a natural side effect of path tracing, eg the unbiased raytracing algorithm we use.
You need to use the suggested tool like hotpixels to remove them.

They are actually deep paths of caustics.

The upcoming beta2.1 version will have a more intelligent render kernel that does not produce these anymore.
