Viruses can only move from person to person when an existing host transfers the virus by coughing, sneezing, or otherwise shedding the virus onto another individual. In earlier drafts of criteria for life, the requirement was that living things must be made of cells. When a virus is not in an infected cell it exists in the form of independent particles. If viruses evolved from living organisms, it would make sense to think of them as alive now. Most scientist says that computer virus are not alive. The virus particles may then either end up on a new potential host or an inanimate object. But on its own, like other viruses, it is inert, not even alive. A biological virus is not a living thing.

Though the concept of using virus behavior for useful purposes was proposed in the earliest documentation of computer viruses, very little published research exists. <. Virus definition, an ultramicroscopic (20 to 300 nanometers in diameter), metabolically inert, infectious agent that replicates only within the cells of living hosts, mainly bacteria, plants, and animals: composed of an RNA or DNA core, a protein coat, and, in more complex types, a surrounding envelope. If you're arguing that a series of concerted chemical reactions which are sufficiently numerous, complex and regulated to bring about something which looks a bit like 'life' then you can say viruses are alive.
