Texture wont delete :S??

Hey im working on some rendering , when i started the project i aded some NOISE texture to my walls but then i decided to delete them now they wont delete they are ruining my renders because the floor has reflection and all the noise dots are all over the walls and some in the floor reflected.

i deleted the texture but it there, i closed my blender, restart my mac, and still the noise texture is there :S

i dont thing that noise is from a texture - it looks like the noise due to low samples (look under the world tab and under Gather there is a samples slider (default 5)) try turning it up to something like 16 or 32 (if you’re that crazy)
