Why could a virus not infect another virus?
Viruses only infect living organisms and since they are not alive, they can not infect other viruses. The question is interesting though.
Why don't viruses and prions qualify as organisms?
Both are missing some key characteristics of life - prions more so than viruses. The most prominent feature that is missing is the ability to reproduce without a host. Viruses can't reproduce without a host cell and prions can't propagate without a normal protein that is transformed into a prion.
Are prions eukaryotic?
Depends on your definition of life. Prions are self replicating (though only in the right conditions. ie inside a host), which is the basic requirement for a living organism. In theory life could have arisen through a similar self replicating molecule.
