The correct answer is B.

OBJ-3.3: The only solution that could stop this from reoccurring would be to use an anti-virus or anti-malware solution with heuristic analysis. The other options might be able to monitor and detect the issue but not stop it from spreading. Heuristic analysis is a method employed by many computer anti-virus programs designed to detect previously unknown computer viruses and new variants of viruses already in the wild. This is behavior-based detection and prevention, so it should detect the issue and stop it from spreading throughout the network. A host-based intrusion detection system (HIDS) is a device or software application that monitors a system for malicious activity or policy violations. Any malicious activity or violation is typically reported to an administrator or collected centrally using a security information and event management system. The UTM is also acting as an IDS in this scenario based on the option presented.
