Cigars have mold, I think - what do I do?

About 3 months ago I purchased my humidor, Andorini, I took all the precautions for preparation. This morning I found a white/grey'ish substance, (mold I think), on my cigars. It is very spotty, powdery looking and the most affected was the ones closest to the humidification unit. Doing some research on the Internet I wiped down the cigars with distilled water and a paper towel, very gently, and used isopropyl alcohol on the interior of the humidor and let to air dry. I'm not sure if its mold or blume, I believe its mold because it not crystalline in nature. I don't see any mold on the interior of my humidor, visible that is. Can my cigars be cured or saved? I've read you can put them in the freezer/frig after cleaning them to stop the mold from coming back, is this good idea? Help?????
