How do I run a virus check?

Running a virus check on your computer is essential for protecting your data and ensuring your system runs smoothly. To perform a virus check, you can use built-in tools or third-party antivirus software to scan your system for malware, viruses, and other threats.

Running a virus check involves several simple steps. Follow this guide to ensure your system is free from harmful software:
