Final answer:
Protease inhibitors are antiviral drugs that block the processing of viral proteins, preventing viral maturation. They are commonly used to treat HIV and other viral infections.
Step-by-step explanation:
Protease inhibitors are common antiviral drugs that target specific viral proteins and prevent viral maturation. They are used to treat various viral infections, one of which is HIV (Human Immunodeficiency Virus).
