It is questionable whether virus is "alive" or not. If it were alive it wouldn't have to do anything to live, it needn't food or drink. Virus is sometimes considered to be just a more complicated molecule.

The proteins in the capsid of the virus allow the virus to attach to the "docking stations" proteins of the host cell. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of needed cell parts.
These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
