Something is out of whack, probably with your glass. Or maybe you have some textures that have R, G, or B values far beyond 240 in them.

Try single-surfaces for your glass, too.

Here's a very quick rendering with the 'Architectural Glass, Normal' preset in Bonzai3d.

or are you maybe using materials with additive layers set to rather high values for glossy surfaces? that's another killer... if so, try to remove the additive layer and check if noise persists. if you absolutely need gloss, try to set up materials without additive layers giving more weight to the high reflective layers or try use coatings.

you can also try to disable reflection and refraction caustic layers in the engine as a last resource... not sure if this was possible within the FZ plugin?
