How to Run Windows Defender Scan on Windows 11

Running a Windows Defender scan on Windows 11 is a straightforward process that helps keep your computer safe from viruses and malware. First, open the Start menu and search for "Windows Security." Once there, select "Virus & threat protection," and then click on "Quick scan." This simple action initiates a thorough check of your files for any potential threats. It’s an easy routine that ensures your system stays protected.

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

Running a Windows Defender scan is crucial for maintaining your computer’s health. Here’s how to do it efficiently.

Step 1: Open the Start Menu

Search for "Windows Security" in the Start menu.

In the Start menu, type "Windows Security" into the search bar. This will lead you to the app you need to get started with your scan.

Step 2: Access Virus & Threat Protection

Once in Windows Security, select "Virus & threat protection."

This section is where all the magic happens. It offers options for different types of scans and shows recent security updates.

Step 3: Initiate a Quick Scan

Click on "Quick scan" to start scanning your computer.

A quick scan checks the most vulnerable areas of your computer for threats. It’s usually done in a few minutes, making it a convenient option for regular checks.

Step 4: Review the Scan Results

The results will show if any actions are needed. You can click on each detected item to learn more and decide whether to quarantine or remove it.

A full scan is more comprehensive, checking all files and programs on your computer. It takes longer but is thorough for deeper issues.
