Running a Windows Defender scan on Windows 11 is a straightforward process that ensures your computer remains protected from malware and other threats. You’ll need to navigate to the Windows Security app, initiate a scan, and let Windows Defender do its thing. Here’s a detailed guide to help you through each step.
How to Run Windows Defender Scan Windows 11
Running a Windows Defender scan in Windows 11 helps to protect your system from malicious software and threats. Follow these steps to ensure your machine is secure.
Step 1: Open Start Menu
Click on the Start button in the lower-left corner of your screen.
The Start menu provides access to all the apps and settings on your computer. It’s your main gateway to the Windows environment, so finding it is crucial.
Step 2: Search for Windows Security
Type “Windows Security” in the search bar and click on the app when it appears.
Windows Security is the hub for all your security needs. It’s where you’ll find the different types of scans and other security features that keep your system safe.
Step 3: Navigate to Virus & Threat Protection
In the Windows Security window, click on "Virus & threat protection."
This section is dedicated to protecting your computer from viruses, malware, and other threats. It’s where you’ll go to initiate a scan.
Step 4: Choose Scan Options
Under the “Current threats” section, click on “Scan options.”
Here, you’ll be able to select the type of scan you want to run. Different scans offer varying levels of thoroughness and duration, so choose based on your needs.
Step 5: Select the Scan Type
Choose between Quick scan, Full scan, Custom scan, or Microsoft Defender Offline scan, then click "Scan now."
Each scan type has its own purpose. A Quick scan checks the most likely places for threats, while a Full scan goes through every file and folder. Custom scan lets you pick specific locations, and the Offline scan runs without Windows fully loaded, useful for stubborn threats.
Step 6: Wait for Scan to Complete
Let the scan run and wait for the results.
Depending on the type of scan, this could take a few minutes to several hours. Make sure your computer stays on and remains connected to power if it’s a long scan.
Step 7: Review Results
Once the scan is complete, review the results and take necessary actions like removing or quarantining threats.
Windows Defender will provide a summary of any threats it finds. You can take immediate action to remove or quarantine these threats to keep your system secure.
After completing these steps, your computer will either be confirmed clean or you will be presented with options to deal with any found threats. This ensures that your system is running smoothly and securely.
