Antivirus software has evolved significantly, with many users now relying on the built-in Windows Security tool, which includes virus and malware protection, a firewall, and browser controls. Windows Security operates automatically, scanning for threats and updating virus definitions, while also providing device security features based on hardware. Although antivirus software offers additional features like VPNs, parental controls, and password managers, the necessity of installing such software depends on personal preference and risk tolerance. Regular updates for both Windows and web browsers are essential for security, as outdated software can be exploited by malware. Engaging in risky online behavior increases vulnerability, and while antivirus programs can enhance security, they are no longer essential for modern Windows systems.
