Something is alive if it can reproduce, respond to changes in his/her/its surroundings, can convert some form of energy into energy to sustain his/her/its self, and has DNA. Thus, a virus is not alive because it can not reproduce on its own-it needs a host. A baby human is alive for the above four reasons (though reproduction is a capacity that will develop with maturity).

Do living things have all the characteristic of life?
You are making your own paradox, if it doesn't have the characteristics then it is not alive, if it does have them, then it is alive. The question is what are the characteristics? Thats a question that is up to us to define, and rather confusing we use several definitions of life depending in what situation we are. For all definitions of life that i know of, bacteria are alive. In the other hand, virus aren't (although they meet some characteristics of some of the definitions, e.g. they evolve, they reproduce [technically they just multiply, its not considered true reproduction,] and so on.)
