Computer viruses and other forms of malware have viewed as a threat to any software system. They have the capability to deliver a malicious infection. A common technique that virus writers use to avoid detection is to enable the virus to change itself by having some kind of self-modifying code. This kind of virus is commonly known as a metamorphic virus, and can be particularly difficult to detect. Metamorphic viruses have a potential to avoid any signature-based detection schemes by implementing code obfuscation techniques in an effort to defeat it. In metamorphic virus, if dead code is added and the control flow is changed sufficiently by inserting jump statements, the virus cannot be detected.
