Which of the following is a primary purpose of using antivirus software?

The primary purpose of using antivirus software is to detect and remove malicious software. Antivirus programs are designed to scan files and software on a system for known threats, such as viruses, worms, Trojans, and more. They employ various techniques, including signature-based detection, heuristic analysis, and behavior monitoring, to identify and mitigate the impact of malware on a computer or network.

By removing malicious software, antivirus solutions help protect the integrity of data, maintain system performance and security, and prevent unauthorized access or data breaches that malware can facilitate. Regularly updated antivirus software is crucial for protecting systems against newly discovered threats and ensuring that vulnerabilities are addressed promptly.

In contrast, managing network resources and blocking unauthorized users refer more to network security and access control measures rather than the core function of antivirus software. Enhancing internet connection speed does not relate to antivirus software's main objectives and falls outside its intended use, as that involves different types of optimization and bandwidth management solutions.
