Handout 5 Virus

With the rapid increasing use of technology in computers, telecommunication and networks is gradually growing over the Internet, various natures of malicious attacks on shared systems and connected computers also are growing at disturbing and shocking rate, which can block data transmission, make network server crash, destroy, corrupt or disclose important files on infected servers/clients or can steal sensitive information. Malwares are designed to damage computer systems leaks information’s to remote servers and affect the systems without the knowledge of owner using system. They include computer viruses, spyware, adware, key logger, rootkits, tailored malware, Trojans, Botnet and dialers etc.I proposed to discuss various Malware classifications, types, their infection and concealment techniques and challenges to financial institutions. I also discuss malware detection techniques employed by antivirus scanners like Dynamic Analysis, Static Analysis, and Heuristic Based Detection etc. to detect malevolent nature.

Abstract— The computers viruses have been become a challenge for computer architecture and self organizing system. There has been considerable interest in computer viruses since they first appeared in 1981 and increasing day by day as they have reached epidemic numbers in many personal computer environments. Viruses have been written about as a security problem, as a social problem, and as a possible means of performing useful tasks in a distributed computing environment. However, only recently have some scientists begun to ask if computer viruses are not a form of computer architecture- a self-replicating organism. Simply because computer viruses do not exist as organic molecules may not be sufficient reason to dismiss the classification of this form of “vandalware” as a form of life. This research paper starts with a description of how computer viruses operate and their history, and of the various ways computer viruses are structured. It then examines how viruses meet properties associated with life as defined by some researchers in the area of computer architecture and self organizing systems. The paper concludes with some comments directed towards the definition of artificially “alive” systems and experimentation.

A computer virus is a piece of software which attaches itself to another program causing undesirable effect on the program. It is attached similar to the way in which biological virus affect other organisms. The synonymous way it works with that of the human virus gave rise to the term computer virus. Computer viruses infect personal computers (PCs) and server. Some viruses create mere annoyance, but others can do serious damage: delete or change files, steal important information, load and run unwanted applications, send documents via electronic mail (e-mail) or even cripple a machines operating system (OS). Random sampling technique on respondents was performed while the data used for the study is collected from primary sources using a well-structured questionnaire. Data collected were logically analyzed using descriptive tool such as percentages and charts and inferential statistical tool such as chi-square. Based on the administered questionnaires the result indicated that viruses can infect computer system through a number of ways such as exchange of flash drive, hard disk and network medium.

The aim of this paper is to examine the effects of globalization on developing economies with emphasis on the origin, nature and relationship between Human Immunodeficiency Virus [HIV] and Computer Viruses [CV's]. The paper begins with introduction where the concept of globalization was reviewed with focus on developing economies. The finding of the paper reveals that Human Immunodeficiency and Computer Virus as part of globalization do more harms than good in all aspects of socioeconomic and technological development in developing economies. Economically, HIV/AIDS and computer/digital related virus has been described as a billion dollar disease through which billions of dollars are being generated from developing economies to developed countries like America and Japan thereby contributing to the under-development of the developing economies. More especially through the production, monopoly and sell of condoms, retro-viral drugs, computer/digital related anti-virus systems. It is also discovered that the developed countries like America and Japan are scientifically and technologically far developed than developing countries which are backward in that respect. The methodology utilized in this paper is secondary source of data. The paper conclude that knowledge about science and technology within the context of globalization are definitely static and obsolete in developing countries compared to developed capitalist countries that operates with exploitation and imperialism. The developing economies found themselves in a quagmire due to total dependence on developed countries for almost everything.
