Windows Defender is Microsoft’s built-in antivirus program that protects your computer from viruses, malware, spyware, and other harmful threats. It is designed to be easy to use and provides real-time protection against malicious software. You can turn on Windows Defender by following these steps:
1. Open the Windows Start Menu and type “Control Panel” in the search bar.
2. In the Control Panel, select System and Security.
3. Under System and Security, select Windows Defender.
4. In Windows Defender, select Settings.
5. Under the General tab, make sure the option titled “Turn on real-time protection (recommended)” is checked. If it is not checked, check the box and click OK.
If you find that your computer is already being affected by viruses or other malicious software, you may need to perform a full scan of your system. To do this, open Windows Defender and select the “Scan Now” button. This will scan your entire system for any viruses or other malicious software. If any threats are found, you will be prompted to remove them.
When Windows Defender is on, it will continually monitor your computer for any malicious activities. If any suspicious activity is detected, Windows Defender will alert you and provide options for responding to the threat. For example, it may prompt you to run a scan, download an update, or take other appropriate action.
It is important to note that Windows Defender does not provide 100% protection from all threats. While it is a powerful tool and can help to detect and remove many types of malicious software, it is not perfect and cannot defend against every type of threat. Therefore, you should also install a separate antivirus program and update it regularly to ensure maximum protection.
Finally, while Windows Defender is a very useful tool, it is important to remember that it is only one part of a complete security solution. To truly protect your computer, you should employ multiple layers of defense and stay vigilant about keeping your system updated.
