This may help you and others had a similar report awhile back

clarkej we were a part of that thread back on 5/29 and told it was not harmful but I would have though it was fixed by now so as not to alarm others whom don’t use osx if it truly was not harmful?

These explain that the warning is meant simply to inform, and why there is nothing to fix
