What main advantage does Anti-Virus Software provide?

Anti-virus software primarily serves to protect systems from malicious software threats, such as viruses, worms, and other forms of malware. This protection is crucial as such threats can compromise personal data, disrupt system operations, and even allow unauthorized access to sensitive information. The software achieves this through various mechanisms, including real-time scanning of files, monitoring downloads, and providing updates to combat newly identified threats.

While system performance, file restoration, and memory optimization are important in computing, they do not capture the primary purpose of anti-virus software. Enhancing system performance and optimizing memory usage might be side benefits of maintaining a clean system, but they are not the core function of anti-virus programs. Similarly, while some tools may assist in recovering deleted files, this is not a fundamental feature of anti-virus solutions. Thus, the main advantage lies in the protection against harmful software to ensure the integrity and security of the system.
