What is the main function of an antivirus program?

The main function of an antivirus program is to detect and remove malicious software. Antivirus software is specifically designed to identify and eliminate threats such as viruses, worms, trojans, ransomware, and other types of malware that can adversely affect a computer system. By scanning files, monitoring system activity, and employing various algorithms, antivirus programs can recognize patterns associated with known malware and respond by either quarantining or deleting harmful files. This protective function is essential for maintaining the integrity and security of data and systems, ensuring that users can operate their devices with reduced risk of infection or compromise.

While improving system performance, managing user accounts, and providing internet security are important aspects of overall system management and security, they are not the primary focus of antivirus software. Instead, the concentration is squarely on the detection and removal of malware, which is crucial for safeguarding sensitive information and ensuring smooth system operation.
