What is anti-virus systems?

Anti-virus systems are software designed to detect, prevent, and remove malicious software (malware) from computer systems. They typically use a combination of techniques, including signature-based detection (identifying known malware), heuristic analysis (detecting suspicious behavior), and behavioral monitoring (observing program actions) to protect against viruses, worms, trojans, ransomware, and other threats. They are commonly used by individuals and organizations to safeguard their data and systems from cyberattacks.
