Antivirus software has evolved from focusing solely on detecting and eliminating computer viruses to providing comprehensive digital security solutions. The modern threat landscape includes advanced persistent threats, ransomware, phishing schemes, fraud apps, and AI-enabled cyber threats, necessitating a broader approach to cybersecurity. Current digital security systems must detect behavioral anomalies, protect user identities, monitor network activity, identify scam links, and provide multi-layered protection across various platforms. Contemporary antivirus solutions now incorporate AI-based threat detection, cloud intelligence, web protection, email security, identity protection, and ransomware monitoring, reflecting a shift from reactive measures to proactive prevention. Users are now active holders of digital identities, and antivirus software is expected to safeguard their entire digital lives.
