How can it be said that a virus is non-living when it has DNA inside? (I know it had no nucleus)
Also, the only way for a virus to reproduce is to inject DNA into a bacterium, correct?
Then, if it wasn't for viruses, would 100% of bacteria then be harmless?
When you say 'unicellular' like an amoeba..does that mean the amoeba itself is the cell? Or there's only one cell in the entire amoeba? Thanks.

A virus is considered non-living precisely because it cannot reproduce on its own. Viruses can infect all kinds of cells, not just bacteria, but, yes, they must transfer their DNA to a host in order to replicate.
Bacteria can cause many problems on their own even without viruses, so they are harmful all on their own. They can kill cells by exploiting them and then lysing them, or many of them put out toxins that harm the host. These aspects don't require viral infection.
In the case of unicellular organisms, the organism and the cell is one and the same. So the amoeba is a cell, and one cell makes up the entire amoeba.

Viruses can be dormant. They appear to be lifeless for long periods of time but can be ''activated'' at any time. AIDS is an example.
