What role does an antivirus software play in cyber security?

Antivirus software is vital in cyber security because its primary function is to protect computer systems from malware and various other threats. This type of software scans files and programs for known malicious signatures and behavioral patterns, allowing it to detect and neutralize viruses, worms, trojans, ransomware, and other types of malicious content.

In addition to identifying and removing malware, many antivirus programs provide real-time protection by continuously monitoring system activity, thus preventing potential threats before they can cause harm. They often include features like web protection, email scanning, and firewall capabilities, which all contribute to a comprehensive security posture against cyber threats.

Other choices reflect functions unrelated to the core task of antivirus software. For instance, web hosting services involve providing server space for websites, which is outside the realm of malware protection. Monitoring employee productivity is related to organizational management practices rather than cyber security. Configuring network hardware pertains to setting up and managing devices like routers and switches, not directly tied to malware defense. Thus, the correct answer revolves around the critical protective role antivirus software plays against cyber threats.
