When plants/animals are infected with a virus, they may produce an antiviral substance that is capable of inhibiting the multiplication of that virus. Identify the correct name of this substance. Virion, Antivirion, Antigen, Interferon

Virus attacks a living body by replicating inside the host cells of the individual. In order to stop the replication cycle of the virus, the host cells produce proteins called as interferons. Interferons are signaling proteins, that heighten the anti-viral response of the neighboring cells.
