Step 1: Disconnect Your PC from the Internet
First things first—cut the malware’s lifeline.
- Turn off Wi-Fi or unplug your Ethernet cable.
- This stops the malware from spreading or communicating with its “boss” online.
Think of it like shutting the door before a thief can run away with your stuff.
Step 2: Boot into Windows 11 Safe Mode
Malware is tricky. It tries to hide while Windows is running normally. Safe Mode makes it easier to catch.
- Press Shift + Restart from your Start Menu power options.
- Go to Troubleshoot > Advanced options > Startup Settings.
- Select Enable Safe Mode with Networking.
Now Windows will load with only the basics, making it harder for malware to hide.
Step 3: Use Windows Security to Run a Full Scan
Windows 11 comes with Windows Security (Defender) built in.
- Go to Settings > Privacy & Security > Windows Security.
- Click Virus & threat protection.
- Choose Full Scan and let it run.
This may take time, but patience pays off. If the malware is caught, Windows will quarantine or remove it automatically.
Step 4: Try a Trusted Malware Removal Tool
Sometimes malware is stubborn and slips past Windows Security. This is where third-party tools help. Popular (and free) ones include:
- Malwarebytes Free
- HitmanPro
- AdwCleaner
Download one, update it, and run a deep scan in Safe Mode. These tools specialize in catching tricky malware that Windows might miss.
Step 5: Delete Temporary Files
Malware often hides in temporary files. Clearing them gives malware fewer places to live.
- Open Disk Cleanup (search it in the Start Menu).
- Select your C: drive.
- Check Temporary files and hit OK.
Boom—clutter gone, and malware has fewer hiding spots.
Step 6: Reset Web Browsers
Ever noticed weird toolbars, search engines, or ads in your browser? Malware loves hijacking browsers.
- In Chrome: Settings > Reset settings > Restore settings to default
- In Edge: Settings > Reset settings > Restore settings to default
- In Firefox: Help > More troubleshooting information > Refresh Firefox
This clears out any nasty add-ons or changes malware made.
Step 7: Update Windows 11 and All Software
Outdated software = open doors for malware.
- Go to Settings > Windows Update > Check for updates.
- Update your apps and drivers too.
This makes your PC stronger against future attacks.
Step 8: Restore or Reset Windows 11 (If Needed)
If nothing else works, don’t panic. You can reset Windows without losing your personal files.
- Go to Settings > System > Recovery.
- Under Reset this PC, choose Keep my files.
- Reinstall Windows 11 cleanly.
This gives your PC a fresh start while keeping your documents safe.
