How to Check for Malware on Windows 11: A Step-by-Step Guide

posted on May 19, 2025

Checking for malware on Windows 11 can seem like a daunting task, but it’s actually quite straightforward. By using built-in tools like Windows Security, you can scan your system to ensure there are no pesky malware threats hiding out. The process involves accessing your security settings and running a thorough scan, which will help keep your computer safe and running smoothly.

Checking for Malware on Windows 11

Scanning your computer for malware is an important step in maintaining your system’s health. Follow these steps to perform a malware check on Windows 11.

Step 1: Open Windows Security

Open the Start menu, type "Windows Security," and press Enter.

Windows Security is your go-to tool for protecting your computer. By opening it, you can access various security settings and scan options.

Step 2: Navigate to Virus & Threat Protection

On the left menu, click on "Virus & threat protection."

This section is specifically designed to handle malware threats. It provides detailed options for scanning and keeping your system protected from malicious software.

Step 3: Start a Quick Scan

Click on "Quick scan" to start a brief scan of your system.

A quick scan checks for any immediate threats lurking in common areas where malware is usually found. This is a good first step to catch any obvious issues.

Step 4: Run a Full Scan

If nothing is found in the Quick Scan, choose "Scan options," then select "Full scan" and hit "Scan now."

A full scan is more thorough, combing through every file and folder on your computer. This may take longer, but it’s worth it for peace of mind.

Step 5: Review Scan Results

Once the scan is complete, review the results for any detected threats.

Windows Security will provide a detailed report of any malware found, along with recommended actions. This helps you know exactly what’s affecting your system and how to fix it.

After completing these steps, your computer will either be declared clean or you’ll receive guidance on removing any detected malware. This process ensures your Windows 11 system is safe from harmful threats.

  • Schedule regular scans to catch malware before it becomes a problem.
  • Use a reputable third-party antivirus for added protection if needed.

  • Keep your operating system and software up to date to patch any security vulnerabilities.
