Computer Virus
This is an excerpt from the paper...
No matter what new technology is developed, the history of humans demonstrates that there will be those who will use it for the improvement of humankind and those who will use it to the detriment of humankind. Such an example is available in the present day with the increasing presence of computer viruses, intentionally created computer “health-threats” capable of infiltrating computers and computer systems causing program and information disaster and economic devastation. The recent arrest of the designer and transmitter of the “Melissa” virus, who was charged with interfering with public communication among various charges, shows the increased significance of this electronic health threat. Further, companies like IBM, whose IBM and IBM-compatible clones are the biggest victims of viruses since they nearly all operate on Microsoft Windows, have spent hundreds of millions of dollars and years of research to find ways of combating computer viruses. Recently, IBM unveiled its Digital Immune System, a sophisticated virus tracking, detection and elimination system mirrored on the processes by which the human body’s immune system fights viruses, “The idea is to create digital white blood cells—much as human beings develop antibodies to biological agents—that will be permanently available on lone. In theory, automatic virus-scouting programs will transmit suspect codes directly to the immune center, where they will be analyzed an

ocuments via email. Most macro viruses are written for Microsoft Word documents, but instances have also been cited in Microsoft Excel and Lotus Ami Pro” (Carden et al. 102).
In addition to viruses there are other modern threats that are similar to viruses. These are known as Trojan horses and hostile applets. Trojan horses do not replicate typically like most viruses. However, Trojan horses can affect individual computers and computer systems even if they do not spread, “Such a Trojan horse program might describe itself as a funky screen saver, but secretly intends to corrupt your hard drive or other parts of your system” (Carden et al. 102). Hostile Active X and Java applets, on the other hand, are quite destructive and do spread. These viruses are designed to send applets or mini-applications automatically through the Internet to system users. They are responsible for systems crashes, loss of data and make data theft a reality. The following list of warning signs was developed by the International Computer Security Association, and it is intended to help users recognize an electronic virus attack:
Computer reboots without reason.
New symbolic pictures or messages show on screen.
