Antivirus software is an essential digital safeguard designed to protect computers, smartphones, and other devices from malicious threats such as viruses, worms, trojans, ransomware, and spyware. It operates by scanning files, emails, and web traffic in real-time, identifying and neutralizing harmful code before it can cause damage. Key features often include automatic updates to detect emerging threats, firewall integration for added security, and tools for scheduled scans and quarantine management. By providing a robust defense against cyberattacks, antivirus solutions help preserve data integrity, ensure system performance, and promote safe online practices for individuals and businesses alike.
