A Wisdom Archive on virus

A virus is a microscopic parasite that infects cells in biological organisms. Viruses are obligate intracellular parasites; they can reproduce only by invading and controlling other cells as they lack the cellular machinery for self-reproduction. The term virus usually refers to those particles that infect eukaryotes (multi-celled organisms and many single-celled organisms), while the term bacteriophage or phage is used to describe those infecting prokaryotes (bacteria and bacteria-like organisms lacking a nucleus ...

A computer virus, Blaster, infected several computer networks across continents recently, disrupting all normal functions, creating havoc in the business world. During the vicious virus attack, the utilisation of the Central Processing Unit (CPU) of the computer - which is its main think tank - was found to be extremely high, overshooting all permissible limits and causing computers to behave in an abnormal fashion.
 
The human mind is often compared to a computer. In fact, we could draw an interesting analogy between a computer virus attack and the mind being plagued by virus-like evil thoughts.

In computer security technology, a virus is a self-replicating program that spreads by inserting copies of itself into other executable code or documents. A computer virus behaves in a way similar to a biological virus, which spreads by inserting itself into living cells. Extending the analogy, the insertion of a virus into the program is termed as an infection, and the infected file (or executable code that is not part of a file) is called a host. Viruses are one of the several types of malicious software or malware. In ... Including:

The Viru Valley is on the north west coast of Peru. Viru Valley - The Viru Valley Project. In 1946 the first attempt to study settlement patterns in the Americas took place in the Viru Valley, led by Gordon Willey. Rather than examine individual settlement sites, Willey wanted to look at the valley as a whole and the way that each village interacted with the others. The study showed that villages were located in places which reflected their relationship with the wider landscape and their neighbours. ... Including:

The Church of Virus (CoV) is a memetically-based atheistic rational "religion". The Church of Virus founded a mailing list in 1995. Virians actively communicate through their BBS. The Church of Virus suggests that all self-conscious intelligences carry and transmit memes, but argues that (almost) everyone has the ability and obligation to carefully select the memes they choose to propagate. The Virian religion holds that there are three virtues to strive to uphold, these being: Reason, Empathy and Vision; along with three "sens ...

The Herpes simplex virus (or HSV) manifests itself in two common diseases marked by watery blisters in the skin or mucous membranes (such as the mouth or lips) or blisters on the genitals. The disease is contagious particularly during an outbreak and at this time incurable. An infection on the lips is commonly known as a 'cold sore' or 'fever blister'. It is sometimes refered to as "the gift that keeps on giving."[1] It is thought that up to 80% of the general population will have the presence of the herpes simplex virus antibo ... Including:

Viruses can be classified in several ways, such as by their geometry, by whether they have envelopes, by the identity of the host organism they can infect, by mode of transmission, or by the type of disease they cause. The most useful classification is probably by the type of nucleic acid the virus contains and its mode of expression. This classification was proposed by Nobel-prize winner David Baltimore. It should be noted that none of these classifications are expected to be phylogenetic, as viruses may not share a common origin. Including:

• Virus classification - Overview

Bliss is a computer virus that infects GNU/Linux systems. It was posted on a Usenet usergroup by its author on February 5th, 1997. When executed, it attempts to attach itself to Linux executable files, which regular users do not have access to. This prevents the executables from running, so users notice it immediately. Although it was probably intended to prove that Linux can be infected, it does not propogate very effectively becaus ...
