Random colored spots coming up on my render

I am working on one of my first renders on blender (That’s my terrible excuse for it looking like crap) and when I render it, random colored spots show up on it. (I use cycles render) Any idea what could be causing this? How can I fix it? The .blend file is attached along with screenshots. Thanks!

Increase the size of the floor plane and increase number of render samples. Attached is increased size of plane (dimensions 20 x 20) and 200 samples


Hi, these random spots called fireflies.
You can try to disable Caustics and add Indirect Clamp, value 2-5.

Cheers, mib

Thanks for the help! I heard fireflies were just random white pixels, thanks though. That really helps a lot!
