A virus infects a cell and forces it to make more viruses.
Explanation:
Viruses cause disease by invading host cells, then taking over the cell and causing it to create more viruses.
The immune system has a variety of ways of detecting that a cell is infected by a virus. There's information about that here: http://bitesized.immunology.org/pathogens-and-disease/immune-responses-to-viruses/
