Antivirus

Antivirus software is a computer program designed to detect, prevent, and remove malicious software, commonly known as malware, from computer systems. It works by scanning files, identifying and quarantining or deleting threats. antivirus programs employ various techniques, including signature-based detection, heuristic analysis, and behavioral monitoring, to identify and neutralize known and unknown threats, helping to protect user data and system integrity. They often run in the background, providing real-time protection, and are regularly updated to combat new and evolving forms of malware. They are also known as endpoint protection software.
