Making a virus more 'deadly' is usually not very good for the virus. If it's host dies, so does it's habitat. Not to mention the host can no longer really spread it.
The Epstein-Barr virus, now there is a successful virus.
What about Lysis? That's a pretty effective way for a virus to spread by destroying the host.
