    This is partly incorrect- even though they can't reproduce viruses are classified as living things- they have biological matter that is not found in non-living things. (Proteins, DNA, and RNA are not possessed by non-living matter. Everywhere these things exist they will be traced back to a life form of some kind or another.)
    The fact that something can't reproduce on its own doesn't mean its not alive (contrary to the bogus science their teaching these days.) - that would be saying that If I get my dog fixed at the vet, all of a sudden its not "alive" anymore, since after all, if the surgery went well, she wouldn't be able to reproduce on her own anymore.
    Further, the replication isn't as simple as this- otherwise, we wouldn't be able to recover from the cold or flu at all. This forgets to mention those all-important things called phagocytes, Lymphocytes, Monocytes, etc. That go after viruses. That, and we also have drugs called antivirals. One of them is Tamaflu.
