How to Run Virus Scan on Windows 10: A Step-by-Step Guide

posted on January 2, 2026

Running a virus scan on Windows 10 is a simple but crucial task to keep your computer safe from harmful software. Start by using Windows Security, an in-built tool that provides reliable protection against malware. Open Windows Security, navigate to ‘Virus & Threat Protection,’ and choose the type of scan you want to run—quick, full, or custom. This scan will help detect and remove any unwanted viruses from your system, ensuring your computer remains secure.

How to Run a Virus Scan on Windows 10

Running a virus scan on Windows 10 is essential to protect your computer from malicious software. Follow these steps to ensure your device is free from threats.

Step 1: Open Windows Security

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

Windows Security is your go-to protection suite on Windows 10. By accessing it, you open the door to various tools that can safeguard your computer against viruses and other threats.

Step 2: Navigate to Virus & Threat Protection

In the Windows Security window, find and select "Virus & Threat Protection."

This section is the heart of your computer’s defense system. It’s where you’ll control your virus scans and monitor your device’s health.

Step 3: Choose Scan Options

Click on “Scan options” under the Current Threats section.

Here, you’ll see different types of scans you can run. Depending on your needs, you might choose a quick scan for fast results or a full scan for thorough investigation.

Step 4: Select and Run a Scan

Pick between Quick, Full, Custom, or Microsoft Defender Offline scan, and click “Scan now.”

Each scan type has its benefits. A quick scan covers the most likely areas for threats, while a full scan digs deep into all files and programs. Choose wisely based on your situation.

Step 5: Wait for the Scan to Complete

Let the scan run and wait for the results.

Patience is key here. The time it takes will vary based on your selected scan and the number of files on your computer. Grab a cup of coffee or tackle another task while it runs.

After completing the scan, Windows Security will display the results, showing any threats and suggesting steps to remove them. Follow these recommendations to clean your system and keep it secure.

Tips for Running a Virus Scan on Windows 10

  • Schedule Regular Scans: Set up automatic scans to run at convenient times to ensure continuous protection.
  • Keep Your System Updated: Regularly update Windows and Windows Security for enhanced features and improved security.
  • Use Custom Scans when Needed: If you suspect an issue with specific files or folders, a custom scan can target those areas directly.
  • Consider a Full Scan Monthly: A full scan once a month provides comprehensive coverage without interrupting daily use.
  • Stay Informed About Threats: Keep an eye on emerging threats and adapt your security settings to combat them.
