How to Run a Virus Scan on Windows 11: A Step-by-Step Guide

Running a virus scan on Windows 11 is straightforward and essential to keep your computer safe from malware and viruses. First, open the Windows Security app from the Start Menu. Then, navigate to the “Virus & threat protection” tab and select “Quick scan.” This will check your computer for any immediate threats. For a more thorough scan, choose “Full scan” or “Custom scan.” Follow the on-screen instructions, and let Windows Security do its job.

Step by Step Tutorial on How to Run a Virus Scan on Windows 11

Running a virus scan on Windows 11 helps ensure your computer is free from harmful software. Follow these steps for a complete guide:

Step 1: Open the Windows Security App

Click the Start Menu and type “Windows Security,” then press Enter.

Opening the Windows Security app is your first step to a virus-free system. The app houses various security options, including virus scans, firewall, and network protection. You can find it easily by typing “Windows Security” in the Start Menu search bar.

Step 2: Navigate to the “Virus & threat protection” Tab

Once in Windows Security, click on the “Virus & threat protection” tab.

This tab is your control center for managing virus and threat protection settings. It offers options like quick scans, full scans, and even custom scans for specific files or folders.

Step 3: Select “Quick scan”

Under “Current threats,” click on the “Quick scan” button to initiate a scan.

A quick scan will check the most vulnerable areas of your computer, usually taking a few minutes. It’s a fast way to ensure there are no immediate threats. However, keep in mind that it might not catch everything.

Step 4: Choose “Full scan” for a More Thorough Check

For a more comprehensive scan, click on “Scan options” and select “Full scan,” then click “Scan now.”

A full scan dives deeper into your system, checking every file and folder. This process can take significantly longer, sometimes up to an hour, but it’s well worth it for peace of mind.

Step 5: Opt for “Custom scan” if Needed

If you need to scan specific files or folders, choose “Custom scan,” then select the areas you want to scan and click “Scan now.”

A custom scan lets you zero in on specific areas of your computer that you suspect might be infected. This is useful if you’ve downloaded a suspicious file or received an alert about a particular folder.

After completing the scan, Windows Security will provide you with a summary of its findings. If any threats are detected, follow the prompts to remove or quarantine them. Your computer should now be safer and more secure.

  • Keep an external backup of important files, in case a virus damages your system.
