Have you been keeping it in a ripening container? If so, that is where it should continue to be kept until it is ready to be eaten (at least according to the recipe I used). It appears that the wheel has some mold growth on it. If so, it should be wiped down with apple cider vinegar to remove it.
I vacuum pack my Havarti at about 2 months old, then refrigerate it, because I don't like the flavor to get stronger.
