What is the primary purpose of an antivirus program?

The primary purpose of an antivirus program is to detect, prevent, and remove malicious software. Antivirus programs are specifically designed to identify various types of malware, including viruses, worms, trojans, ransomware, and spyware. They use a combination of signature-based detection (recognizing known malware patterns) and heuristic analysis (detecting new, previously unknown viruses or changes to existing ones) to provide protection. By continually scanning files and monitoring system behavior, antivirus software helps ensure that a device remains secure against malware threats.

Other options, while important in a comprehensive IT and cybersecurity strategy, relate to different functions. Optimization of system performance focuses on improving the efficiency and speed of the device rather than protecting it from threats. Creating backups is critical for data recovery but does not involve direct malware protection. Managing software updates ensures that programs and their security features are up to date but is a separate process from the core function of detecting and eliminating malware.
