One effective way to do this is by using Windows Defender, which is a built-in antivirus software in Windows 10. Here are some steps to use Windows Defender for keeping your PC safe:

1. Open Windows Security: Go to the Start menu and search for Windows Security. Open the app.
2. Run a Quick or Full scan: Click on the “Virus & threat protection” option and then click on the “Quick scan” or “Full scan” option. Quick scans are faster but less thorough, while full scans take longer but provide more comprehensive results.
3. Schedule a scan: You can also schedule a scan to run automatically at a specific time. Go to the “Virus & threat protection” option, click on “Manage settings,” and then turn on the “Periodic scanning” option. Choose the frequency and time for the scans.
4. Update Windows Defender: Windows Defender updates automatically, but you can also check for updates manually. Go to the “Virus & threat protection” option, click on “Manage settings,” and then click on “Check for updates” under the “Virus & threat protection updates” section.
5. Use Windows Defender Firewall: Windows Defender also includes a firewall that can protect your PC from unauthorized access. Go to the “Firewall & network protection” option and make sure it is turned on.
6. Customize settings: Windows Defender also includes several customizable settings that you can adjust to suit your needs. Go to the “Virus & threat protection” or “Firewall & network protection” options and click on “Manage settings” to view and adjust the settings.

By following these steps and using Windows Defender, you can protect your PC from malware and viruses and ensure that your data and information remain secure. Remember to keep Windows Defender updated and to scan your PC regularly to ensure that it is always protected.

How to schedule a regular scan with Windows Defender to ensure ongoing protection.

Step 1: Open Windows Security

To open Windows Security, click on the Start menu and search for "Windows Security." Alternatively, you can press the Windows key + I to open Settings and then click on "Update & Security" and then "Windows Security."

Step 7: Check the results

Once the scan has completed, you can review the results by clicking on "Scan history" under the "Virus & threat protection" settings. You'll be able to see any threats that were detected and what actions were taken to remove them.

By scheduling regular scans with Windows Defender, you can ensure that your PC remains protected from the latest malware and other threats.
