What is the purpose of anti-virus software?

The purpose of anti-virus software is primarily to block malicious programs from harming the computer. This type of software is designed to detect, quarantine, and remove viruses and other types of malware that can compromise system security, steal sensitive information, or disrupt normal operations. By actively monitoring the system for suspicious activity and scanning files for known threats, anti-virus software helps to maintain the integrity and security of the computer system. This function is crucial in protecting users from the various risks associated with malicious software, which can lead to data loss, identity theft, and other serious consequences.

While anti-virus software might have some indirect effects on system performance through its scanning processes, its primary role is centered around security rather than performance enhancement. Additionally, anti-virus software does not manage computer networks or focus on file recovery; those functionalities are typically handled by network management tools and data recovery software, respectively.
