Solution
An antiviral protein released from infected and dying cells is interferon
Explanation:
Interferons are antiviral proteins released by infected and dying cells. They help protect uninfected neighboring cells by inducing an antiviral state that inhibits viral replication. This response is part of the body’s innate defense against viruses, distinct from antibodies, antigens, or antiserum.
