If viruses are considered alive, they would be the only non-cellular lifeforms.
But the term "life" may only include activities that occur at a cellular level. Without cells it would be very difficult to distribute and use nutrients, which is part of the definition of biological life.
Viruses and the related form called prions are proteins that affect cells but have none of their autonomous chacteristics. This is why there is debate over whether viruses should be considered "alive."

Why would a biologist expect any newly discovered organism to be made of cells?
Biologists would expect any newly discovered organism to be made of cells because all living organisms that have been studied thus far are composed of cells. Cells are fundamental units of life that provide structure, carry out functions, and contain genetic material necessary for life processes. This cellular structure is a key characteristic shared by all known forms of life.
