ChromeOS is designed with multiple layers of security to protect against malware and viruses: * Read-only file system: Most of the operating system is stored in a read-only partition, making it difficult for malware to modify critical files. * Verified boot: Ensures the integrity of the operating system during bootup, preventing tampering by unauthorized software. * Sandboxing: Isolates different processes and websites, limiting the potential damage of any malware that manages to get through. * Automatic updates: Regularly delivers security patches and updates to address vulnerabilities. While ChromeOS doesn't come with traditional antivirus software, its built-in security features provide robust protection against most threats.
