The last and what some people consider to be the worst of the security problem is computer viruses. Computer viruses have been around for a decade but they became infamous when the Michelangelo virus caused a scare on March 6, 1992(Dyson 265). According to the National Computer Security Association in Carlisle, Pennsylvania, there are six thousand known viruses worldwide and about two hundred new ones show up every month (Booht 51). These viruses are spread quickly and easily and can destroy all information on a computer's hard drive. Although we do ...

- ... areas in South America, had bred successfully in captivity and some captive-born birds have been released in the wild, giving biologists good reason to be optimistic about similar success for the California condor.Computer Viruses A computer virus is an illegal and potentially damaging computer program designed to infect other software by attaching itself to any software it contacts. In many cases, virus programs are designed to damage computer systems maliciously by destroying of corrupting data. If the infected software is transferred to or accessed by another computer system, the virus spreads to the other system. Viruses have become a serious problem in recent years, and currently, thousands of known virus programs exist (Reed 85-102)b. Three types of viruses are a boot sector virus, file virus, and Trojan horse virus. A boot sector virus infects the. When the infected boot program executes, the virus is loaded into the computers memory. Once the ...
- 34: AIDS - What's new ?
- ... brain. In 1983 and 1984, French and U.S. researchers independently identified the virus believed to cause AIDS as an unusual type of slow-acting retrovirus now called "human immunodeficiency virus" or HIV. Like other viruses, HIV is basically a tiny package of genes. But being a retrovirus, it has the rare capacity to copy and insert its genes right into a human cell's own chromosomes (DNA). Once inside a ... illness can unknowingly infect others. On average, the dormant virus seems to be triggered into action three to six years after first invading human cells. When switched on, viral replication may speed along, producing new viruses that destroy fresh lymphocytes. As viral replication spreads, the lymphocyte destruction virtually sabotages the entire immune system. In essence, HIV viruses do not kill people, they merely render the immune system defenceless against other "opportunistic: infections, e.g. yeast invasions, toxoplasmosis, cytomegalovirus and Epstein Barr infections, massive herpes infections, special forms of pneumonia (Pneumocystis carinii - ...

- ... the world due to the misuse of medicines, such as antibiotics and antivirals, the destruction of our environment, and shortsighted political action and/or inaction. Viral hemorrhagic fevers are a group of diseases caused by viruses from four distinct families of viruses: filoviruses, arenaviruses, flaviviruses, and bunyaviruses. The usual hosts for most of these viruses are rodents or arthropods, and in some viruses, such as the Ebola virus, the natural host is not known. All forms of viral hemorrhagic fever begin with fever and muscle aches, and depending on ...

- ... been discovered, but research is being done to discover other carcinogens to keep people aware and safe. There are also many different biological agents, which cause cancers. The most common biological agents are the oncogenic viruses that commonly bring about the formation of neoplasms in some smaller animals. Also some of these viruses are thought to cause human cancers, and one has even been proven to cause leukemia. These viruses can be split into DNA viruses and RNA viruses, depending on their genetic structure. The DNA viruses generally insert the genetic information straight into the cells of their host. The RNA virus, contrasting, requires ...
- 38: A Look Into The Computer Virus
- ... ever consider that we are also exchanging files with anyone and everyone who has ever handled them in the past. If that sounds like a warning about social diseases, it might as well be. Computer viruses are every bit as insidious and destructive, and come in a vast variety of strains. A computer virus tears up your hard drive and brings down your network. However, computer viruses are almost always curable diagnosed, and cures for new strains are usually just a matter of days, not months or years, away. Virus, a program that "infects" computer files (usually other executable programs) by inserting ... files' copies of itself. This is usually done in such a manner that the copies will be executed when the file is loaded into memory, allowing them to infect still other files, and so on. Viruses often have damaging side effects, sometimes intentionally, sometimes not. (Microsoft Encarta 1996) Most viruses are created out of curiosity.

On some occasions, these cyber-felons perform even more malicious acts, such as infecting systems with "viruses," computer programs that "infect" the systems by latching onto other programs and eventually destroying them.
