Any foreign substance that enters the body, such as viruses, pollen, dust, snake venom, etc., is considered an antigen and triggers the immune system to create antibodies.
Antivirus are those substances that inhibit the action of viruses in the body. Antivirals are medicines that support your body's defences against certain viruses that might harm you. Medicines that fight viruses are also preventive. They can shield you against viral illnesses and the transfer of viruses to other people.
At the point of infection, virus-infected cells release interferons as cytokine barriers. Interferons create a protective layer surrounding the infected cell to shield neighbouring cells from further infections.
Virion is an infective particle that is composed of genetic material that is either DNA or RNA and a protein coat. So, they are capsid-encapsulated viruses with DNA or RNA molecules.
