Abstract

Viruses and malware are serious threats to system security. There are different types of viruses today that it has become difficult to provide a precise definition [7]. Polymorphic and metamorphic viruses are two well known kinds of viruses. A polymorphic virus has the ability to change its signature every time by slightly modifying itself when it replicates, thus avoiding detection.
The first polymorphic virus was developed in the year 1990 [16], and later many generator kits were developed that simplified the work of writing a computer virus. These kits enabled people with minimal knowledge to develop their own new viruses. There are also many packers and wrappers available that can be used to make viruses more difficult to detect.
In this project, we analyze different polymorphic viruses and try to develop an application that will encrypt, mutate, and protect any polymorphic virus, thereby making it more difficult to detect.
