All viruses have a protein shell surrounding their nucleic acid called a capsid (or coat).
Some viruses also have an envelope, which is made of a lipid membrane. This is completely distinct from the capsid.

Virusoids have capsids, Viroids do not have capsids
Both Virusoids and Viroids have RNA, Prions do not have Any RNA just protein, Virusoids rely on Helper Viruses to replicate, Viroids do not require helper viruses. There is a large controversy on whether any of these forms of viruses are living organisms because they only exist within a host cell. Viroids and Virusoids infect a cell by infecting the nucleus and a cells mechanism for DNA replication
