Metamorphic / polymorphic malware fundamental principles malware must be defined semantically as the very same virus, worm, bot, key logger etc is likely to exist in different physical forms the techniques of polymorphism and polymorphic and metamorphic malware are. Essay polymorphic & cloning computer viruses the generation of today is growing up in a fast-growing, high-tech world which allows us to do the impossibilities of yesterday with the help of modern telecommunications 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. All that a cloning virus really does is look at what operations the computer is executing and react and adapt to them by making more copies of itself this is the serious flaw with cloning viruses: all the copies of itself look the same.
Metamorphic and polymorphic malware are two categories of malicious software programs (malware) that have the ability to change their code as they propagate in spite of the permanent changes to. Despite considerable effort, buffer overflow attacks remain a major security threat today, especially when coupled with self-propagation mechanisms as in worms and viruses this paper considers the problem of designing network-level mechanisms for detecting polymorphic instances of such attacks the. Techniques to make the entire polymorphic virus as undetectable as possible virus creators turned to other methods of hiding malware like breaking the code into several segments.
A computer virus is a type of malicious software that, when executed, replicates itself by modifying other computer programs and inserting its own code when this replication succeeds, the affected areas are then said to be infected with a computer virus. A computer virus is a program or piece of code that is loaded onto your computer without your knowledge and runs against your wishes viruses can also replicate themselves all computer viruses are man-made some people distinguish between general viruses and worms a worm is a special type of virus. A computer virus is a program that infects host les and spreads the infection from one le to another much like a biological virus  simple virus replication.

Polymorphic malicious executable scanner by api sequence analysis j-y xu, a h sung, p chavez, s mukkamala computer viruses are more complex and difficult than their original versions to detect, often requiring viruses [10, 11] and heuristics based static analysis techniques have been proposed by researchers for virus detection. Some polymorphic viruses can even take several days to catch once they are known because they re-write their identifying code or signature and produce a slightly different clone of themselves consequently, anti-virus scanning strategies can never be 100% effective, and are reactive rather than proactive in nature. Polymorphic computer programs are computer programs, which have object code that varies between instances of the computer program for example, polymorphic viruses are computer viruses, which have object code that varies between instances of the virus.
