The document discusses the life cycle of viruses and the mechanisms of various antiviral agents that inhibit virus attachment, penetration, and replication. It mentions specific agents such as amantadine, rimantadine, acyclovir, cytarabine, zidovudine, lamivudine, zanamivir, and peramivir. These agents play critical roles in targeting different stages of viral replication.
