The Ebola virus makes people bleed and dehydrate. What in it would cause people to bleed? It must be that it thins out the blood vessels so that blood seeps through them, so, if the blood vessels were to remain in tact there would be less risk. If people were to create a virus that feeds off of Ebola, like a ebola eating virus, then they would effectively kill it off. This could be done by mutating white blood vessels so that they become dependant on Ebola to survive, then make them actually eat the virus itself. This can be done by agitating the white blood vessels so that they become aggressive, or, by making the Ebola carry good things that the white blood vessel wants. If it comes to making things eat the Ebola, maybe we could put a vicious cells type in a container with the Ebola, and, then having nothing to eat will take a liking to the Ebola eventaully. After a while if it keeps eating ebola it will mutate into a Ebola eating virus. Al lthat is needed is another virus that doesn't have to be stronger since they can populate the body with plenty of this new virus. Viruses don't take long to mutate so we could have an Ebola eating virus in a matter of days I presume, as long as Ebola is produced to keep the new virus satisfied.
