How to check for malware on Windows 11: A step-by-step guide

Got a shiny new Windows 11 PC and worried about malware? No problem! You can check for malware on your computer by using the built-in Windows Security app. It’s quick, easy, and in just a few steps, you’ll have peace of mind knowing your computer is safe.

Step by Step Tutorial: Checking for Malware on Windows 11

Before we jump into action, let’s understand what we’re about to do. These steps will guide you through checking your Windows 11 machine for any nasty malware that might be lurking around.

Step 1: Open Windows Security

Open the Windows Security app by clicking the Start menu and typing "Windows Security."

The Windows Security app is your main hub for all things security-related on your Windows 11 PC. It’s where you’ll find virus & threat protection, account protection, firewall, and more.

Step 2: Select Virus & Threat Protection

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

This is where you’ll see any current threats, scan options, and health reports of your device. It’s your go-to spot for checking up on the safety of your system.

Step 3: Run a Quick Scan

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

A quick scan will check the areas of your system most likely to be affected by malware. It’s fast and efficient, but if you want a more thorough check, you can opt for a full scan, which takes longer but covers the entire system.

Step 4: Review the Results

Once the scan is complete, review the results to see if any threats were found and take action if necessary.

If the scan finds anything, Windows Security will offer options to deal with the threat, such as cleaning it or quarantining it.

After completing these steps, your computer will have been checked for malware, and any found threats will have been dealt with accordingly.

  • Keep an eye on your system’s performance; a sudden slowdown might indicate malware activity.
