Step-by-Step Tutorial on How to Run Windows Defender Scan on Windows 11

Let’s dive into the details of how to run a Windows Defender scan on Windows 11. This process will help you detect and remove any potential threats on your computer.

Step 1: Open Windows Security

First, click the Start button and type “Windows Security” into the search bar.

You should see the Windows Security app appear in the search results. Click on it to open the app. This is your hub for managing all security features on your Windows 11 device.

Step 2: Navigate to Virus & Threat Protection

Once you have the Windows Security app open, look for the “Virus & threat protection” option and click on it.

This section is where you will find all the tools you need to protect your computer from malicious software.

Step 3: Choose Your Scan Type

In the Virus & threat protection section, click on “Quick scan” to run a fast scan, or “Scan options” to choose a more detailed Full scan.

A Quick scan checks the most common areas where malware might be hiding, while a Full scan goes through every file and folder on your computer. Choose the one that suits your needs.

Step 4: Start the Scan

After selecting your scan type, click the “Scan now” button to begin the process.

Windows Defender will start scanning your computer right away. This might take a few minutes for a Quick scan or several hours for a Full scan, depending on the size of your hard drive and the number of files.

Step 5: Review the Results

When the scan is complete, Windows Defender will provide a summary of any threats found and actions taken.

If any threats are detected, follow the prompts to remove or quarantine them. This ensures your system remains clean and secure.

Once you’ve completed these steps, Windows Defender will keep you updated on any threats it finds and what actions it took. Regular scans are a good habit to keep your system safe.

Tips for Running Windows Defender Scan on Windows 11

  • Regular Scans: Schedule regular scans to ensure ongoing protection. A weekly Full scan can catch threats that a Quick scan might miss.
  • Update Definitions: Always keep your virus definitions up to date. These updates help Windows Defender recognize the latest threats.
  • Use Custom Scans: If you suspect a specific file or folder, use the Custom scan option to check only those areas.
  • Real-Time Protection: Enable real-time protection in Windows Security settings to stop threats before they cause harm.
  • Offline Scan: For stubborn malware, use the Windows Defender Offline scan, which runs before Windows starts and can remove hard-to-detect threats.
