No. Second Life (SL) is completely safe, if you download directly.
There are alternate SL Viewers that are user created that can be used in place of the official one referenced above. Those could contain viruses.
As a normal precaution: Make sure to run any program (executable) files through a virus scanner before installing.
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.
The Official Second Life viewer is not known to contain any viruses.
The official Second Life viewer released by Linden Lab and the official Second Life website do not contain any known viruses. It has been reported that third party viewers in the past have caused security risks however these are no longer in use.
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.
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 do not belong to any of the five kingdoms of life.
The influenza virus is not living any more than other viruses. It has no life processes.
Viruses don't fit into the kingdoms of life because they aren't considered to be living things, even though they have DNA. Weird right?
Since viruses are not alive they can not have life processes.
Many, if not most biologists do not consider viruses living. So, they are not on any phylogenetic tree that I know of. They may have a phylogeny that I am unaware of, though.
No, any Second Life account can be deleted at any time via the official website at no cost.
