Thomas Morris created the first virus as such: Creeper, which could infect IBM 360 on the ARPANET (the predecessor of the Internet) and show an on-screen message saying “I’m the creeper, catch me if you can”. To eliminate it, a virus called Reaper was created to search for it and destroy it”…………………...PANDA SECURITY ( 2011) Malware Overview Retrieved from http://www.google.com/images?rlz=1T4ADFA_enUS391US392&q=virus+clipart&um=1&ie=UTF-8&source=u

engineering crosses the coded DNA barrier and utilizes very powerful (and unnatural) laboratory techniques for transferring genetic material directly between plants and animals. Using these techniques, genes from any plant, animal, virus, or other organism, including a human, can be inserted into any other organism. Therefore, scientists have been able to take “beneficial genes” from some plants or animals and splice them into the DNA of fruits and vegetables. This modification process can make them resistant

difference is that web-based malware infections are pull-based and that the resulting command feedback loop is looser. To characterize the nature of this rising thread, we identify the four prevalent mechanisms used to inject malicious content on popular web sites: web server security, user contributed content, advertising and third-party widgets. For each of these areas, we present examples of abuse found on the Internet. Our aim is to present the state of malware on the Web and emphasize the

like a biological virus passes from person to person. Computer viruses are created by people by writing code to create the virus, and designing the attack phase which could be a message or initiate the destruction of a piece of hardware. Early viruses were pieces of code embedded in legitimate programs, like games or word processors. A virus is a small piece of software that piggybacks on real programs; it might attach itself to a program and each time the program runs the virus runs too, and they

modified organism, or GMO, is any organism that has had its DNA modified in some way through genetic engineering techniques. About eighty-five percent of the time, GMOs have been altered with DNA from another organism, for example; bacterium, plant, virus or animal. This harmful organism is not healthy for people even though we eat them every day. Many people claim that GMOs are not bad for you because they are in almost everything we eat. However, if someone is allergic to something and it is in the

A computer virus is a computer program that can replicate itself[1] and spread from one computer to another. The term "virus" is also commonly, but erroneously, used to refer to other types of malware, including but not limited to adware and spyware programs that do not have a reproductive ability. Malware includes computer viruses, computer worms, Trojan horses, most rootkits, spyware, dishonest adware and other malicious or unwanted software, including true viruses. Viruses are sometimes confused
