Virus - Wikipedia, the free encyclopedia In the case of the Hepatitis B virus, the T-number is 4, therefore 240 proteins assemble to form the capsid. The capsid of a phage, a bacterial virus, remains on the outside. As of April 2005, the Marburg virus is attracting widespread press attention for an outbreak in Angola. en.wikipedia.org /wiki/Virus   (3550 words)

Computer virus - Wikipedia, the free encyclopedia In a common parlance, the term virus is often extended to refer to worms, trojan horses and other sorts of malware; however, this can confuse computer users, since viruses in the narrow sense of the word are less common than they used to be, compared to other forms of malware. Sometimes the word "virus" is also considered an acronym which stands for "Vital Information Resource Under Siege", but this only started relatively recently (meaning it is a backronym instead) and is unrelated to the initial use of the word "virus" for computer malware. The term "virus" is often used in common parlance to describe all kinds of malware (malicious software), including those that are more properly classified as worms or trojans. en.wikipedia.org /wiki/Computer_virus   (4539 words)

Virus (life science) - MSN Encarta Eastern equine encephalomyelitis virus, an alphavirus, replicates in mosquitoes and is transmitted to wild birds when the mosquitoes feed. The virus replication cycle can be as short as a couple of hours for certain small viruses or as long as several days for some large viruses. Thus, wild birds and perhaps mammals and reptiles serve as the virus reservoir, and mosquitoes serve as vectors essential to the virus life cycle by ensuring transmission of the virus from one host to another. encarta.msn.com /encyclopedia_761575740/Virus_(life_science).html   (2024 words)

Bugs in the News - What the Heck is a Virus? A virus is not a bacterium, nor an independently-living organism. The virus uses the cell's machinery and some of the cell's enzymes to generate virus parts which are later assembled into thousands of new, mature, infectious virus which can leave the cell to infect other cells. A virus enters a cell by first attaching to a specific structure on the cell's surface via a specific structure on the virus surface. people.ku.edu /~jbrown/virus.html   (1463 words)

Virus information and help The first virus was written by Fred Cohen in 1983, and later coined in a 1984 research paper. As mentioned earlier a virus is capable of being either memory resident where the virus first loads into memory and then infects a computer or non-memory resident where the virus code is only executed each time a file is opened. Because some viruses are memory resident, as soon as a diskette or program is loaded into memory, the virus then attaches itself into memory and then is capable of infecting any file on the computer you have access to. www.computerhope.com /vlist.htm   (1369 words)

Virus definition - Medical and health information on the common cold and flu Herpes simplex virus and the hepatitis- B virus are DNA viruses. The Dutch microbiologist Martinus Beijerinck (1851-1931) was the first person to use the term "virus" for the invisible disease-causing material that he showed to be self-replicating. A virus invades living cells and uses their chemical machinery to keep itself alive and to replicate itself. www.medterms.com /script/main/art.asp?articlekey=5997   (547 words)

virus - Wiktionary The word virus is derived from the Latin virus, meaning roughly "poison", "slime" or "venom", and still retains this meaning.

Therefore, the virus imports RNA polymerase or transcriptase as a part of the virus structure. www.blc.arizona.edu /INTERACTIVE/virusL2.95/virus.html   (343 words)

Viruses A virus is basically a tiny bundle of genetic material—either DNA or RNA—carried in a shell called the viral coat, or capsid, which is made up of bits of protein called capsomeres. Upon landing on an appropriate host cell, a virus gets its genetic material inside the cell either by tricking the host cell to pull it inside, like it would a nutrient molecule, or by fusing its viral coat with the host cell wall or membrane and releasing its genes inside. If the virus is an RNA virus, it must first turn its RNA into DNA using the host cell's machinery before inserting into the host DNA. www.microbe.org /microbes/virus1.asp   (815 words)

Fred Cohen & Associates Traces were included to assure that the virus would not spread without detection, access controls were used for the infection process, and the code required for the attack was kept in segments, each encrypted and protected to prevent illicit use. Although this is a source level virus and could be detected fairly easily by the originator of any given program, it is rare that a working program is examined by its creator after it is in operation. The Unix virus is independent of the computer on which it is implemented, and is therefore able to run under IDRIS, VENIX, and a host of other UNIX based operating systems on a wide variety of systems. www.all.net /books/virus/part5.html   (2112 words)

Virus-host interactions For example, newborn mice are susceptible to infection with herpes virus type 1 due to a defect in the ability of macrophages to prevent replication of the virus. Intrinsic antiviral activity is the ability of macrophages to resist infection with a virus and extrinsic antiviral activity is the ability of macrophages to kill other cells infected with virus. Some viruses such a lymphocytic choriomeningitis virus produce large amounts of immune complexes in the circulation which lodge in the vascular beds and in the kidneys where they fix complement and result in tissue damage. pathmicro.med.sc.edu /mayer/vir-host2000.htm   (2999 words)

What is virus? - A Word Definition From the Webopedia Computer Dictionary Even such a simple virus is dangerous because it will quickly use all available memory and bring the system to a halt.

LOVE LETTER VIRUS - A Simple Program that Rocks the World And because the files being deleted by the virus are not really significant, the damages done by this virus are restricted mainly to lost manhours in containing the virus and fixing its damages as well as the inability of users to access their system until proper safeguards have been implemented therein. The virus took only over 300 lines of VBS programming codes and yet it proved to be a nightmare to a lot of network administrators around the world within the first 24 hours of its attack. There is a second element of the virus however that could have given the author of the virus (and subsequent copycat writers) access to confidential password information from the infected system. www.newsflash.org /2000/05/hl/hl012106.htm   (1962 words)
