If they're floating around in the air or sitting on a rock, they're inert ... not alive at all. They don't do any of the normal things we associate with living organisms. But if they come into contact with a suitable living cell they infect and take over the cell, and reproduce themselves. All viruses only exist to make more viruses. With the possible exception of bacterial viruses, which can kill harmful bacteria, all viruses are considered harmful, because their reproduction causes the death of the cells which the viruses entered.If a virus contains DNA, it inserts its genetic material into the host cell's DNA. If the virus contains RNA, it must first turn its RNA into DNA using the host cell's machinery, before inserting it into the host DNA. Once it has taken over the cell, viral genes are then copied thousands of times, using the machinery the host cell would ordinarily use to reproduce its own DNA. Then the host cell is forced to encapsulate this viral DNA into new protein shells; the new viruses created are then released, destroying the cell. </blockquote>
