Checking for viruses on Windows 11 is a crucial task to keep your computer running smoothly and securely. You can accomplish this by utilizing the built-in Windows Security tool, which is user-friendly and effective. To start, you’ll need to open Windows Security, navigate to the Virus & threat protection section, and perform a quick or full scan. Follow the on-screen prompts to review and address any detected threats. With just a few clicks, you can ensure your system is safe from malicious software.
How to Check for Viruses on Windows 11
Let’s dive into the detailed steps to check your Windows 11 computer for viruses using the built-in security features.
Step 1: Open Windows Security
To begin, click the Start button and type “Windows Security” in the search bar, then select the app from the search results.
The Windows Security app is a powerful tool that comes pre-installed on all Windows 11 devices. It offers a comprehensive suite of protections against malware and other threats.
Step 2: Navigate to Virus & Threat Protection
Once the app is open, locate and click on the “Virus & threat protection” option from the menu on the left.
This section is where all your antivirus activities live. It’s like the command center for your computer’s defenses, giving you access to scans, updates, and protection history.
Step 3: Choose a Scan Option
Click on “Quick scan” to perform a fast check of the most vulnerable areas or select “Scan options” for a full system scan.
A quick scan usually takes a few minutes and checks common threat areas, while a full scan might take longer but is more thorough, assessing your entire system for any hidden threats.
Step 4: Start the Scan
Select your preferred scan type and click on “Scan now” to initiate the process.
During this step, Windows Security will actively search your system for viruses and other threats. You can carry on with your work, as it runs quietly in the background.
Step 5: Review and Address Threats
Upon completion, Windows Security will display any detected threats and recommended actions. Follow the instructions to remove or quarantine any issues.
The results page will provide you with a detailed report of the scan, including what was found and how to handle it. This is your opportunity to ensure your PC is clean and safe.
After completing these steps, your computer will be scanned for viruses, and Windows Security will inform you of any threats it finds, along with recommendations for next steps. If no threats are found, you’re good to go.
