Polymorphic & clone Computer Viruses     The generation of to twenty-four hours is growing up in a fast-growing, high-tech worldwhich allows us to do the impossibilities of yesterday. With the help of moderntelecommunications and the speedy growth of the personal figurer in the averagehousehold we atomic number 18 adequate to(p) to talk to and share information with multitude from allsides of the globe. However, this vast amount of information transport hasopened the doors for the computer "computer computer computer virus" of the future tense to flourish. As timepasses on, so-called "viruses" are becoming more and more adaptive and dangerous.No longer are viruses merely a queerness among computer users and no longer arethey mere nuisances. Since many people depend on the data in their computerevery day to make a living, the risk of catastrophe has increased tenfold. Thepeople who render computer viruses are now becoming frequently more adept at makingthem harder to detect and eliminate. These so-called "polymorphic" viruses areable to clone themselves and change themselves as they need to avoid detection.This form of " intellectual viruses" allows the virus to have a form of artificialintelligence. To understand the mien a computer virus works and spreads, firstone essential understand some basics about computers, specifically pertaining to theway it stores data. Because of the callousness of the damage that these viruses maycause, it is important to understand how anti-virus programs go about detective workthem and how the virus itself adapts to meet the ever changing conditions of acomputer. In much the same way as animals, computer viruses live in colonialenvironments. In this case, the computer acts as a form of ecosystem in whichthe virus functions. In order for someone to adequately understand how and whythe virus adapts itself, it must first be shown how the environment isconstantly ch anging and how the virus can interact and deal with these changes. in that location are many forms of computers in the world however, for simplicitys sake,this paper will focus on the most common form of personal computers, the 80x86,better known as an IBM compatible machine. The computer itself is run by aspecial piece of electronics known as a microprocessor. This acts as the brainsof the computer ecosystem and could be said to be at the top of the food chain.A computers primary function is to hold and make data and that is where avirus comes into play. Data itself is stored in the computer via memory. Thereare two general categories for all memory random entranceway memory (RAM) andphysical memory (hard and floppy diskettes).
