anti-virus

The term is a modern compound, directly combining two classical elements to address a contemporary technological threat. The prefix "anti-", of Greek origin via Latin, carries its ancient sense of opposition or protection "against" something. It is attached to "virus", a Latin word originally denoting a poisonous substance or venom. This medical metaphor was adopted in computing during the late 20th century to describe self-replicating malicious code. Thus, "antivirus" logically means "against the poison," describing software designed to oppose and neutralize digital infections, perfectly bridging the classical roots to their modern application.
