Vysottsky created a game called CoreWar, based on the theory of Von Neumann and in which programs fought between each other, trying to occupy as much memory as possible and eliminating opposing programs. This game is considered the precursor to computer viruses. In 1972, Robert 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

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

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
