Abstract

False-Positive detection and classification by anti malware product have been a cause of serious concern by sector leaders in the anti-virus program vendors and respective clients. Irrespective of incredible strides achieved by anti-malware program vendors, by proactively utilise machine learning and signatures heuristics pattern to detects and classify suspicious file and URLs links in real-time by anti-malware programs. The effect of constant mutation of recent malware sample, resulting in a high number of False-Positives seem to a portrayed severe question regarding the integrity of the vendor’s product. This paper proposes an anti-malware detection method expected to improve accurate detection and classification accuracy; that reduces the likelihood of False-Positives detection using security scoring system in conjunction with traditional machine learning technologies. Where suspicious MD5 Hash samples submission from Microsoft Yara Hits through MalShare repository were analysed and matched with various hosts to determine Vendors Detection Rate (VDR) used as security score for this study. Experimental result features and metadata acquired are compared in conjunction with classification models to limit False Positive dictation from suspicious samples, thereby creates a more efficient anti-malware program. The study experiments on two well-performing classifications, algorithm K-NN Classifier and Support Vector Machine (SVM) used for classification and regression to determine the accurate classification of malware sample, for effective False-Positive reduction. The findings from False-Positive results indicate that when the file types are compromised, it gives ample room for inaccurate performance in detection and classifications of anti malware programs with the relative change in file size of the sample.
Keywords: Anti-malware, False-Positive, Obfuscation, Malware Detection, & Classification.
