viruses

Contagious microscopic particles

Viruses are infectious agents that replicate only inside living cells.

In biology, a virus causes disease by hijacking cellular machinery: the flu virus, HIV is a virus.

In computing, a virus is malicious code that spreads by attaching to programs or files: My computer caught a virus.

Figuratively, ideas or content that spread rapidly are said to go viral.
