What is meant by the term "Antivirus" in network security contexts?

The term "Antivirus" in network security contexts refers specifically to software that detects and removes malware. This encompasses a range of malicious software, including viruses, worms, Trojans, ransomware, and spyware, among others. Antivirus software works by using various techniques to identify, quarantine, and eliminate these threats, ensuring that systems remain secure and free from harmful programs that could compromise data integrity or user confidentiality.

In addition to detection and removal, modern antivirus solutions often include protective measures such as real-time scanning, behavioral analysis, and automatic updates to ensure ongoing defense against the latest malware threats. This is crucial in today's rapidly evolving cyber threat landscape, where new forms of malware are constantly being developed and distributed.

The other options focus on different aspects of network security but do not pertain to the specific role of antivirus software. Organizing network traffic is more related to network management and optimization, ensuring software updates relate to maintaining software integrity and performance, while filtering unwanted web content pertains to content security and access controls. Thus, the definition of antivirus rests firmly within the domain of malware detection and remediation.
