Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These parts can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
Since viruses are not alive they can not have life processes.
Neither - viruses do not eat. There are debates about whether viruses are a form of life, or organic structures that interact with living organisms.
No
None. Viruses are acellular. Many biologists do not consider viruses to be living things in part because they are acellular. Look at any phylogeny (tree of life). Viruses are not on them.
Viruses have the ability to greatly affect life on earth. Many viruses, such as HIV and influenza have killed millions of people. By studying viruses, scientists are able to develop vaccines that will protect people (and animals) from viruses.
Neither, viruses are unique to themselves and don't belong to any classification of life. Viruses are not considered living things because they do not perform all the functions of life therefore they are considered organic particles.
The only life function that a virus shares with a cell is reproduction. Both cells and viruses reproduce in some way.
reproduction
they are hard to get along and they get to egear.

Currently as of 18/05/2013 There are no reported viruses on the official Second Life website. Although it is not impossible for any website to become infected with a virus, Second Life is considered to be a safe site. I have personally been a Second Life resident since 2006 and have never encountered a virus.
One exception to the characteristic of life is viruses. Viruses are considered non-living because they cannot carry out the basic functions of life on their own and require a host cell to replicate.
