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.

Structure: anti (against) + virus (infectious agent) - anti: From Greek, via Latin, meaning "against, opposite, in place of". A prefix indicating opposition or prevention. - virus: From Latin, meaning "poison, slimy liquid, venom". In modern computing, it refers to a malicious program that replicates itself.
