Antivirus software, also known as antimalware, is a computer program used to prevent, detect, and remove malicious software. These malicious programs, commonly referred to as viruses, include a wide range of threats such as viruses, worms, trojan horses, ransomware, spyware, adware, and other types of malware. Antivirus software works by scanning files and programs for known patterns of malicious code, often called signatures. When a potential threat is identified, the antivirus software can quarantine the file, delete it, or attempt to repair it.

Modern antivirus programs employ several detection methods. Signature-based detection relies on a database of known malware signatures. Heuristic analysis examines program behavior for suspicious activities that are characteristic of malware, even if the specific threat is not yet known. Sandboxing executes suspicious files in an isolated environment to observe their behavior without risking the main system. Real-time protection continuously monitors system activity and scans new files as they are accessed or downloaded.

Regular updates to the antivirus software and its signature database are crucial for effective protection against emerging threats. Antivirus programs are a fundamental component of cybersecurity for personal computers, servers, and mobile devices, helping to safeguard data and maintain system integrity. While highly effective, antivirus software is not a foolproof solution and should be used in conjunction with other security practices like strong passwords and caution when opening email attachments or downloading files from untrusted sources.
