Malware can slow down your Windows 11 computer and put your personal information at risk. Removing it promptly is important to keep your system safe and running smoothly. This guide will walk you through the simple steps to clean your system and protect it from malware.

Each step is explained in detail to help even beginners follow along without confusion. You don’t need advanced technical skills to get your PC back to normal.

By the end, you will know how to detect, remove, and prevent malware on Windows 11 effectively. Let’s get started with some quick checks before diving into the removal process.

Following this guide carefully will help ensure a complete cleanup and better system security.

Quick Note: Before You Begin

Before starting the malware removal process, make sure to:

• Back up important files to an external drive or cloud storage. This protects your data in case something goes wrong.
• Disconnect from the internet to prevent malware from communicating with external servers during cleanup.
• Have your Windows 11 user account with administrator rights ready, as some steps require admin privileges.
• Close all running applications to avoid interference with malware scans and removal.

Step 1: Restart Your PC in Safe Mode

Safe Mode starts Windows with only the essential programs and services. This helps prevent malware from running and makes removal easier.

1. Click the Start button and select Settings (gear icon).
2. Go to System > Recovery.
3. Under Advanced startup, click Restart now. Your PC will restart and show a menu.
4. Choose Troubleshoot > Advanced options > Startup Settings > Restart.
5. After restart, press 4 or F4 to enter Safe Mode.

Starting in Safe Mode limits malware activity so your cleanup tools can work effectively.

Step 2: Run Windows Security Scan

Windows 11 comes with built-in antivirus software called Windows Security. It can detect and remove many common types of malware.

1. Press Windows key + I to open Settings.
2. Go to Privacy & Security > Windows Security > Virus & threat protection.
3. Click on Quick scan to start scanning your system.
4. If threats are found, follow the prompts to remove or quarantine them.

A quick scan checks common areas where malware hides. If you suspect deeper infection, consider running a full scan:

• In the same section, click Scan options.
• Select Full scan and click Scan now. This scan can take an hour or more but is thorough.

Step 3: Use a Trusted Third-Party Malware Scanner

Sometimes, Windows Security may not detect all malware. Using an additional reputable scanner can help find hidden threats.

Some well-known free options include:

• Malwarebytes: Excellent at detecting adware and spyware.
• Bitdefender Free Edition: Lightweight and effective antivirus.

To use Malwarebytes:

1. Visit malwarebytes.com and download the free version.
2. Install and open Malwarebytes.
3. Click Scan and wait for it to finish.
4. Quarantine any detected threats.

Running multiple scanners increases your chances of catching all malware.

Step 4: Remove Temporary Files

Malware often hides in temporary files. Clearing these can remove malware remnants and free up disk space.

1. Press Windows key + R, type cleanmgr, and press Enter.
2. Select your system drive (usually C:) and click OK.
3. Check the boxes for Temporary files, Recycle Bin, and other unwanted files.
4. Click OK and then Delete Files to confirm.

This process cleans clutter where malware could hide and helps improve system performance.

Step 5: Check and Remove Suspicious Startup Programs

Malware often sets itself to start automatically with Windows. Disabling suspicious startup programs prevents them from running again.

1. Right-click the Start button and select Task Manager.
2. Click the Startup tab.
3. Look for unfamiliar or suspicious programs with high impact on startup.
4. Select any suspicious program and click Disable.

If you’re unsure about a program, search its name online before disabling it. Disabling legitimate programs can cause issues.

Step 6: Reset Your Web Browsers

Malware can hijack your web browsers by changing settings or installing harmful extensions. Resetting browsers restores default settings.

For Microsoft Edge:

1. Open Edge and click the three dots (…) in the top right corner.
2. Select Settings > Reset settings.
3. Click Restore settings to their default values.
4. Confirm by clicking Reset.

Repeat similar steps for other browsers like Chrome or Firefox.

Step 7: Update Windows and Security Software

Keeping your system and antivirus updated helps protect against new malware threats.

1. Press Windows key + I to open Settings.
2. Go to Windows Update.
3. Click Check for updates and install any available updates.
4. Open your antivirus program and update its virus definitions.

Regular updates patch vulnerabilities that malware exploits.

Alternative & Advanced Options

If malware persists, you can try these advanced methods:

• Use Microsoft Defender Offline scan: This boots your PC into a special mode to scan deeply. Access it via Virus & threat protection > Scan options > Microsoft Defender Offline scan.
• Use System Restore: If malware appeared recently, restoring your PC to an earlier state can remove it. Search for Create a restore point and use System Restore.
• Reset or reinstall Windows: As a last resort, resetting Windows will remove all apps and files, so backup is crucial.
