As already well put by other guys, those are radiosity artifacts, and it's pain
to clean them out... there are two parameters that must be balanced, 'count' and
'error_bound'. I will upload image in a separate post to clarify.

Generally, I combat these artifatcs by using:
-textures, image maps - not plain flat surfaces
-complex lightning scene - not single point light or sky dome
-actual environment, room, background - not object suspended in empty black
space
-focal blur - even a subtle amount works miracles
-large renders (5000+ px) - then apply small amount of gauss or other blur
filter
