Antivirus software is a critical tool for threat detection as it is specifically designed to identify, quarantine, and eliminate malware, viruses, and other malicious threats targeting computer systems. By utilizing signature-based detection as well as heuristic and behavior-based techniques, antivirus programs can recognize known threats and detect potential new ones based on their behavior or characteristics. This capability makes antivirus software a foundational component of an organization's cybersecurity strategy, helping to protect systems from various types of malware attacks, including worms, Trojans, and ransomware. While data backup solutions are essential for recovering data after an incident, they do not actively detect threats. User training programs play a vital role in helping employees recognize and respond to potential security threats but do not inherently provide detection capabilities. Application whitelisting is a method to control which applications are allowed to run on a system, aiding in prevention rather than detection. Thus, among the options provided, antivirus software stands out as the primary tool for proactively detecting threats in real-time.
