A lot of differing views as to weather viruses are alive I don't think you could
come to any conclusion if you asked a number of biology teachers. Viruses have DNA
or RNA and are able to reproduce, though they need a host cell. they also follow all
of the rules for evolution so I think they are alive, though only in the most basic
of definitions. they are able to weaken them breading successive generations of them
together, all the interbreeding weakens them. And they can kill them with radiation.

Generally a live virus is considered to be able to initiate a complete
infection in the right host, while a weakened or 'dead' virus provokes a
immunological reaction mainly, is what I think I remember. Whether it's
alive is really not an interesting issue.
Have a look at http://www.xs4all.nl/~wgods/: here an old colleague of mine
vents his opinion on HIV...

Sorry: I should have added: http://www.xs4all.nl/~wgods/ and look up 'The
Moronic Majority', chapter 'The condom conspiracy'.

I know, I just thought I'd bring it up and see what people said :-)

The best definition of life I've seen so far is "something that can
cause a local decrease in entropy". If I remember correctly, according
to this definition, virii would be alive, but prions (mad cow's disease)
wouldn't.

Once, I saw a electron microscope picture of DNA next a computer generated
model.

Neat trick, interbreeding an asexual organism.
