posted on July 1, 2025

Checking for malware on your Windows 10 PC is crucial for keeping your system safe and running smoothly. To do this, you can use the built-in Windows Security app, which offers a comprehensive way to scan your computer. By following a few simple steps, you can detect and remove malware, ensuring your computer stays in top shape.

How to Check for Malware on Windows 10

Scanning for malware involves using Windows Security, which helps you protect your PC from harmful software. Follow these steps to carry out a thorough check.

Step 1: Open Windows Security

To begin, click on the Start menu and type "Windows Security" into the search bar.

Once you find it, click to open. The Windows Security app is your gateway to the various built-in protection tools that Windows 10 has to offer.

Step 2: Navigate to Virus & Threat Protection

Within Windows Security, look for the "Virus & Threat Protection" tab. Click on it.

This section is essential for protecting your system against viruses and other malicious threats. It provides real-time protection and options for different types of scans.

Step 3: Choose Scan Options

Select "Full scan" and then click "Scan now" to start the scanning process.

A Full scan is thorough, checking every nook and cranny of your computer for signs of malware. It may take some time, but it’s worth it for peace of mind.

Step 5: Review Results

After the scan completes, review the results to see if any threats were detected.

If malware is found, Windows Security will provide options to remove or quarantine the threats. Follow the prompts to secure your computer.

After completing these actions, your computer should be free from malware. If threats were detected and removed, you might notice improved system performance. Regular scans are recommended to maintain security.
