SAMAWI PY - 1996 VL - 27 IS - 1 SP - 8 EP - 15 JO - Iraqi Journal for Computers and Informatics المجلة العراقية للحاسبات والمعلوماتية SN - 2313190X 25204912 AB - Many papers have been published about manipulating computer viruses; instructions that impact a computer system and after a period of incubation and reproducion, activate and demonstrate their presence.mest Viruses were designed to attack microcomputers, sincce microcomputers are widely used nowadays, and have simple operating systems which result in lack of quality of their security systern. Connecting computers with networks and using copies of programs from unreliable sources such as bullet in board systems will increase the :of viral contact and the spread of viruses. Data Encryption disguises data flowing through a network so that it is unintelligible to any one monitor the data, Encryption techniques can also be used to detect file modification which may caused either by unithorized users or by viruses. This paper concern in viruses atracking users on system files (.exe and com) in microcomputer systems, where viruses Types, how they work, and anti-virus strateigies are going o scussed. Finally, a dccction strategy depending on Encryption techniques built the operating systems Suggested to improve PCs Security and preventing unauthorized users from inserting into programs commands that will cause system corruption.
