Viruses dont have a cell membrane. Instead, they have a protein sheath.
If you mean what are viruses then they are nonliving strands Rna surrounded by a protein coat

No, animal cells do not have a protein coat. Only viruses have a protein coat.
A protein coat, or capsid, is a structural component of viruses that encases and protects their genetic material. While it does not contain viruses itself, it is a crucial part of the virus structure. The protein coat helps in the attachment and entry of the virus into host cells. Therefore, while the protein coat is associated with viruses, it does not contain them in isolation.
Antibodies
interferon
Reverse transcriptase.
Viruses are surrounded by a protein coat called a capsid, which protects their genetic material. Some bacteria have an outer protein coat called a capsule, which provides protection and helps them adhere to surfaces.
Because viruses can not reproduce or produce protein without a host cell
protein, nucleic acid /\All viruses are made up of a core of genetic material ... nucleic acid, which is either DNA or RNA. This is surrounded by a protein coat.
