摘要: The proliferation of malware has presented a serious threat to the security computer systems. Traditional signature-based anti-virus systems fail detect polymorphic and new, previously unseen malicious executables. In this paper, resting on analysis Windows API execution sequences called by PE files, we develop Intelligent Malware Detection System (IMDS) using Objective-Oriented Association (OOA) mining based classification. IMDS is an integrated system consisting three major modules: parser, OOA rule generator, classifier. An OOA_Fast_FP-Growth algorithm adapted efficiently generate rules for A comprehensive experimental study large collection files obtained from laboratory King-Soft Corporation performed compare various detection approaches. Promising results demonstrate that accuracy efficiency our out perform popular software such as Norton AntiVirus McAfee VirusScan, well previous data which employed Naive Bayes, Support Vector Machine (SVM) Decision Tree techniques.
