Nowadays, the number of new malware samples discovered every day is in millions, which undermines the effectiveness of the traditional signature-based approach towards malware detection. To address this problem, machine learning methods have become an attractive and almost imperative solution. In most of the previous work, the application of machine learning to this problem is batch learning. Due to its fixed setting during the learning phase, batch learning often results in low detection accuracy when encountered zero-day samples with obfuscated appearance or unseen behavior. Therefore, in this paper, we propose the FTRL-DP online algorithm to address the problem of malware detection under concept drift when the behavior of malware changes over time. The experimental results show that online learning outperforms batch learning in all settings, either with or without retrainings.
