Checking for malware on Windows 11 is crucial for keeping your system safe and secure. To accomplish this, use Windows Security to perform a quick scan, and consider a more thorough scan using additional tools if needed. Regular checks and updates are vital for maintaining your computer’s health.
How to Check for Malware on Windows 11
To ensure Windows 11 is free from malware, follow these simple steps using built-in tools and settings. The steps will guide you through using Windows Security, the main defense built into your system, to check for and address any malware threats.
Step 1: Open Windows Security
Begin by accessing Windows Security through the Start menu.
You can search for “Windows Security” in the Start menu’s search bar and click on the app. It serves as the hub for all your security settings and actions, making it your first stop on this journey.
Step 2: Navigate to Virus & Threat Protection
Select the Virus & threat protection tab to proceed.
This section houses options for scanning your system and keeping an eye out for potential malware. You’ll find quick and full scan options here, which are essential for keeping your system clean.
Step 3: Run a Quick Scan
Select the Quick Scan button to start scanning your system for common threats.
A quick scan checks the most vulnerable parts of your system where malware typically hides. It usually takes just a few minutes and is the easiest way to catch anything suspicious swiftly.
Step 4: Review Scan Results
Once the scan is complete, examine the results for any detected threats.
Windows Security will generate a report of any threats it finds. If any items are flagged, you can take immediate action, such as removing or quarantining the malware.
Step 5: Consider a Full Scan
If needed, choose Full Scan for a more comprehensive check-up.
A full scan is more thorough, exploring every nook and cranny of your system. It takes longer than a quick scan but ensures nothing slips through the cracks.
After completing these steps, your computer should be free of any detected malware. If threats are found and addressed, your system will be cleaner and safer. You may also consider scheduling regular scans to maintain ongoing protection.

- Schedule weekly scans to keep your system consistently in check.
