While humans may not like to get "sick", part of natural selection and the life cycle include disease. Pneumonia has been termed "The Old Man's Friend", aiding with the end of life. The same would be true with the animal kingdom.
Over the last century, a number of vaccines have been developed using mutated viruses, or similar viruses to highly dangerous viruses. For example, the cowpox virus provided immunity for smallpox, and was instrumental in the eradication of that deadly disease.
In recent times, viruses have been used as transport mechanisms to introduce genes into cells, and will likely be central in a new field of gene therapy.

This creates a symbiotic relationship between the host and the virus. This may sound improbable, but viruses normally can only target one species and then only one type of cell of that particular species, allowing for this.
In fact, the use of viruses to combat bacteria was attempted in a toothpaste a number of years ago, but was unsuccessful mainly because the manufacturers failed to convince enough people that viruses could actually be good for them.

This has happened naturally in a few occasions, hence why much of human DNA is derived from viruses (retroviral DNA).

Attenuated or inactivated viruses serve to make vaccine against a particular disease. Viral enzymes can be useful for large scale production and sale in research sector.
