Comparison Of Computer Viruses
The compilation of a unified list of computer viruses is made difficult because of naming. To aid the fight against computer viruses and other types of malicious software, many security advisory organizations and developers of anti-virus software compile and publish lists of viruses. When a new virus appears, the rush begins to identify and understand it as well as develop appropriate counter-measures to stop its propagation. Along the way, a name is attached to the virus. As the developers of anti-virus software compete partly based on how quickly they react to the new threat, they usually study and name the viruses independently. By the time the virus is identified, many names denote the same virus. Another source of ambiguity in names is that sometimes a virus initially identified as a completely new virus is found to be a variation of an earlier known virus, in which cases, it is often renamed. For example, the second variation of the Sobig worm was initially called "Palyh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Duplornaviricota
''Duplornaviricota'' is a phylum of RNA viruses, which contains all double-stranded RNA viruses, except for those in phylum ''Pisuviricota.'' Characteristic of the group is a viral capsid composed of 60 homo- or heterodimers of capsid protein on a pseudo-T=2 lattice. Duplornaviruses infect both prokaryotes and eukaryotes. The name of the group derives from Italian ''duplo'' which means double (a reference to double-stranded), ''rna'' for the type of virus, and -''viricota'' which is the suffix for a virus phylum. Classes The following classes are recognized: * ''Chrymotiviricetes'' * ''Resentoviricetes'' * ''Vidaverviricetes ''Cystovirus'' is a genus of double-stranded RNA viruses which infects bacteria.

Zilligvirae
''Adnaviria'' is a realm of viruses that includes archaeal viruses that have a filamentous virion (i.e. body) and a linear, double-stranded DNA genome. The genome exists in A-form (A-DNA) and encodes a dimeric major capsid protein (MCP) that contains the SIRV2 fold, a type of alpha-helix bundle containing four helices. The virion consists of the genome encased in capsid proteins to form a helical nucleoprotein complex. For some viruses, this helix is surrounded by a lipid membrane called an envelope. Some contain an additional protein layer between the nucleoprotein helix and the envelope. Complete virions are long and thin and may be flexible or a stiff like a rod. ''Adnaviria'' was established in 2020 after cryogenic electron microscopy showed that the viruses in the realm were related due to a shared MCP, A-DNA, and general virion structure. Viruses in ''Adnaviria'' infect hyperthermophilic archaea, i.e. archaea that inhabit very high temperature environments such as hot springs ...
