That's how virus' are not considered life even though they [...] and reproduce No they don't reproduce. And is exactly the point why they are not considered life.
They rely on other life to metabolize. they do not metabolize. They are dead. They do nothing.
A virus is a particle that contains genes, that is it. It has a hull that protects it from some harm, aka: it does not get easy destroyed. If it hits a cell of the right properties - that is the cell membrane - it injects its genetic code into the cell. The cell mistakes as a bunch of codes coming from itself, and executes them. Which leads to the production of the amino acids, and genes, which compose the original virus. "By magic" those reassemble at the inside of the cell membrane, or outside of the cell when the explodes due to over production of virus particles. "By magic" means, plenty of viruses are self assembling. For some non imaginational reason, the particles simple stick to each other in the correct way to result in a virus again.
So it is only one virus in, and one virus out. Not one new virus is produced. Good to know.
