A virus is a non-living obligate intracellular parasite. They can only replicate inside of a living cell as they lack the necessary enzymes and molecular building blocks to be self sufficient. Viruses can be classified by structure (icosahedral, enveloped, complex etc), genome (retroviruses have an RNA genome) or by the route through transcription (Baltimore classification).
