How to Use a Malware Scanner in Windows 11: A Step-by-Step Guide

Scanning your computer for malware is a crucial step in keeping your system secure. With Windows 11, there are built-in tools that make this process easy. By following a few simple steps, you can ensure your computer is free from any malicious software.

Step by Step Tutorial to Use a Malware Scanner in Windows 11

Before we dive into the steps, it’s important to know that using a malware scanner can help prevent, detect and remove malware from your computer. Let’s get started.

Step 1: Open Windows Security

Open the Windows Security app by searching for it in the Start menu.

Windows Security is the built-in security center for Windows 11. It includes various tools to protect your computer, including a malware scanner.

Step 2: Select Virus & threat protection

Click on “Virus & threat protection” in the Windows Security app.

This section is where you can scan your computer for viruses and other threats. It also shows you the history of any detected threats.

Step 3: Click on Quick scan

Select the “Quick scan” button to start scanning your computer for malware.

A Quick scan will check the areas of your computer most likely to contain malware. It’s a good starting point, but keep in mind it doesn’t scan every single file.

Step 4: Wait for the scan to complete

Allow the scan to run and wait for it to complete.

Depending on your computer’s speed and the number of files you have, this could take a few minutes or longer. Be patient and let the scan finish.

Step 5: Review the results

After the scan is complete, review the results and take action if any threats are found.

If malware is detected, Windows Security will provide options to resolve the issue, such as removing or quarantining the malicious software.

After completing the malware scan, your computer should be free from common threats. Make sure to run scans regularly or enable automatic scans for continuous protection.
