I still disagree with Scott. IMO Steve and Polytropon put it straight.

Is a biological virus (not a computer virus) a form of life or a thing?
It depends on the definition of living things and things, as well as
the understanding of different kinds of viruses.

To me the "importance" and the "impact" in a historical context are part
of a definition.

To me MS- and DR-DOS are operating systems and to me a biological virus
is a life form, even while I'm aware, that a virus doesn't fit to almost
all definitions of a life form.
