Day to day the number of malwares are increasing and approximately every day thousands of new malwares are introduced to the internet via various resources. Thus it becomes a need for the sake of one’s safety that a system to detect and curd these malwares has to be developed. MALWARE DETECTION TECHNIQUES Techniques used for malware detection can be broadly classified into two categories: anomaly-based detection and signature-based detection. A special type of anomaly based detection is specification-based detection. Fig. 2. Types of Malware Detection Techniques Signature Based Malware Detection Technique Signature based detection uses the knowledge of what is considered as malicious to finds out the maliciousness of the program under inspection.[3] Commercial antivirus scanners look for signatures which are typically a sequence of bytes within the malware code to declare that the program scanned is malicious in nature. Basically there are three kinds of malwares: basic, polymorphic, metamorphic malwares. In basic malware the program entry point is changed such that the control is transferred to malicious payload. Detection is relatively if the signature can be found for the viral code. Fig. 3. Basic
