How to Check for Viruses on Windows 10

Keeping your Windows 10 computer safe from viruses is crucial. By following a few simple steps, you can easily scan your system for harmful viruses and malware. You’ll use the built-in Windows Security tool, which is designed to protect your computer from threats without the need for third-party software. This guide will walk you through running a virus scan and ensuring your system stays secure.

Step-by-Step Tutorial: Checking for Viruses on Windows 10

To effectively check for viruses on your Windows 10 computer, follow these steps to use the Windows Security tool. This built-in feature helps scan and protect your system from potential threats.

Step 1: Open Windows Security

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

Windows Security is your computer’s built-in safety tool, making it easily accessible and ready to use. Once open, you’ll find various options for protecting your PC.

Step 2: Navigate to Virus & Threat Protection

In the Windows Security window, click on "Virus & Threat Protection."

This section is dedicated to scanning your computer for viruses. It provides different scan options and keeps your system updated against the latest threats.

Step 3: Run a Quick Scan

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

A Quick Scan checks the most common areas where viruses typically hide. It’s a fast way to ensure there’s nothing harmful lurking in your files.

Step 4: Review Scan Results

After the scan, check the results to see if any threats were found.

If threats are detected, Windows Security will guide you through the steps to remove them. It’s important to address any found threats immediately to keep your system secure.

Step 5: Perform a Full Scan (Optional)

For a more thorough check, click "Scan Options" and select "Full Scan."

A Full Scan examines every nook and cranny of your system. It takes longer, but it’s the best way to ensure your computer is completely virus-free.

Once you’ve completed these steps, your computer will either be confirmed virus-free, or you’ll have instructions to remove any threats. Regular scans help maintain your computer’s health, so it’s good to make this a routine task.

  • Schedule regular scans to ensure continuous protection.
  • Use real-time protection to catch threats as they occur.
