Computer Viruses While technology advances have brought many benefits to society there have also been technological abuses (1). In today’s generation, with the help of the Internet and the rapid growth of the personal computer in the average household, we are able to talk to and share information with people from all sides of the globe (2). Unfortunately this transformation of data has opened the doors for a new era of high tech crime – the computer virus. The Internet is now a complex gateway

Abstract— Computer viruses are widely recognized as a significant computer threat. The “birth rate” of new viruses is high and increasing due to global connectivity, and technology improvements can accelerate their spread. In response to this threat, some contemporary research efforts are aimed at creating computer virus immune systems. This paper analyses the computer viruses and attacks and also some countermeasures to prevent them. In particular, we discuss Intrusion Detection and Prevention techniques

A computer virus is a program that is designed to damage your computer, programs, and files. Like a virus in a living thing, a computer virus can spread if it is not removed. Some viruses are more dangerous than others. One of the most common places for a computer virus to appear is on a file found on the Internet or attached to an E-mail. Computer viruses didn’t really exist until the mid 1980s. The first computer viruses were created in university labs to demonstrate how much of a threat the vicious

An Overview of Computer Viruses in a Research Environment Matt Bishop Department of Mathematics and Computer Science Dartmouth College Hanover, NH 03755 ABSTRACT The threat of attack by computer viruses is in reality a very small part of a much more general threat, specifically attacks aimed at subverting computer security. This paper examines computer viruses as malicious logic in a research and development environment, relates them to various models of security and integrity, and examines current
