Malware is a computer program developed with the intent of disrupting, stealing, and compromising a computer system. In recent advances in technology and internet use, malware has become the major problem in computer society. In this research, an optimal K-nearest Neighbor (KNN) based malware detection and classification model is proposed. The proposed malware detection model is based on application programming interface (API) call sequence analysis and classification. The dataset is collected from an online Kaggle data repository which consists of 42,797 malicious application programming interface (API) call sequences and 1,079 non-malicious application programming interface (API) call sequences. The Nearest Neighbor (KNN) algorithm is applied to the dataset to create a model that detects malware. Finally, the accuracy of the proposed KNN based malware detection model is evaluated, and the result shows that the accuracy of 98.17% is achieved in the detection of malware using the model. The proposed model is significantly essential for detecting real-time intrusion on computer systems.

Important Announcements

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
