that is a bit of the overlap, all cells want to replicate themselves be it anything from virus, plant, or animal cells its just that plant and animal cells stop themselves from replication and sometimes forget (causing cancer) and virus cells are single celled (if you can even really call them a "cell") and have no downsides to replicating as much as they desire
The exact same thing goes for viruses.

There are no "virus" cells. No virus has ever been isolated in the history of Virology.
