In high-school they teach the very basics and oversimplify science, it's easier to teach kids that way. People like to put things into tidy categories, yet nature almost never fits into them. Putting things into categories can be useful at times, but we have to remember that the categories are usually artificial and should not get in the way of understanding the diversity out there.

"Viruses straddle the definition of life. They lie somewhere between supra molecular complexes and very simple biological entities. Viruses contain some of the structures and exhibit some of the activities that are common to organic life, but they are missing many of the others. In general, viruses are entirely composed of a single strand of genetic information encased within a protein capsule. Viruses lack most of the internal structure and machinery which characterize 'life', including the biosynthetic machinery that is necessary for reproduction. In order for a virus to replicate it must infect a suitable host cell".
