The computer technology has emerged as a necessity in the people day to day life to deal with various aspects like education, banking, communication, entertainment, etc. Computer system's security is threatened by weapons named as malware to accomplish malicious intention of its writers. Various solutions are available to detect these threats like AV Scanners, Intrusion Detection System, and Firewalls etc. These solutions of malware detection traditionally use signatures of malware to detect their presence in the authors' system.
