The component that is found in viruses and not in cells is the protein capsid (though it seems there might have been a typo in your question with "spsid").
Viruses consist of a protein coat called a capsid that encases their genetic material, and they lack many structures that are found in cells, such as cytosol, ribosomes, and nucleolus. Cells, on the other hand, have a complex structure with these organelles.
