Yes. All viruses are composed of a nucleic acid surrounded by a protein capsid. When the capsid is not present, the the infectious nucleic acid is called viroid. When the nucleic acid is not present, the infectious protein coating is called prion.

If a virus has one, yes, and it's often referred to as a "protein coat."

Protein capsid.
Capsidecapsid
The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
