Windows 11 Malware Protection
Malware protection helps detect and block malicious files, applications, websites, and behavior. Effective protection is supported by updates, cautious downloads, and secure account habits.
Malware includes more than traditional viruses. Ransomware, spyware, trojans, and malicious downloads can target different parts of a Windows 11 computer. A layered security plan should be paired with backups and careful browsing.
No antivirus replaces judgment. Do not open unexpected attachments, install pirated software, or ignore repeated warnings from the operating system or security software.
What to consider
- Install updates from trusted sources.
- Back up important documents to a separate location.
- Review detection notices and follow the recommended remediation steps.
