What is Windows Defender and how do I use it to protect my computer?

Windows Defender is a built-in antivirus and security solution provided by Microsoft for its Windows operating systems, including Windows 10 and Windows 11. It is designed to help protect computers from various threats, such as viruses, malware, spyware, and phishing attacks. Windows Defender offers real-time protection, which means it continuously monitors the system for potential threats and provides automatic updates to its virus definitions to ensure that it can defend against the latest threats. To use Windows Defender to protect a computer, a user should ensure that it is activated and regularly updated. This can typically be done by accessing the Windows Security application, which can be found through the Start menu. Once in Windows Security, the user can navigate to the "Virus & threat protection" section, where they will find options for running quick or full scans of the system, as well as the ability to view security alerts and recommendations. Another essential feature within Windows Defender is its ability to schedule regular scans. Users can set up these scans to run at specific times, ensuring that the system is routinely checked for any malicious software. Additionally, Windows Defender provides options for controlled folder access, which helps protect sensitive files from unauthorized changes by harmful applications. It is also wise to take advantage of the cloud-delivered protection feature, which allows the software to analyze threats in real-time and respond accordingly. Users should keep an eye on the Microsoft website for other security tips and best practices to optimize their computer's protection.
