Isn't metabolism one definition of life? If so, they're not alive.

Weird, i didn't even got a server timeout, which is usualy the cause.
Okay, this got me curious. From the wikipedia article on viruses:
Viruses are considered by some biologists to be a life form, because they carry genetic material, reproduce, and evolve through natural selection, although they lack the key characteristics, such as cell structure, that are generally considered necessary criteria for defining life. Because they possess some but not all such qualities, viruses have been described as "organisms at the edge of life" and as replicators.
They're not compromised of cells, can't self regulate, and can't replicate on their own and other organisms have to do that for them. The last point being important to our criteria for living. I was never taught as a biologist by anyone that they were alive

"Obligate intracellular parasite" was drilled and showed up on multiple exams, along with all that you mentioned. I've also heard "escaped cellular machinery."
Absolutely fascinating...if a tad frightening.
