How to Recover Your Windows PC from a Ransomware Attack Without Paying a Dime

 


How to Recover Your Windows PC from a Ransomware Attack Without Paying a Dime

Ransomware attacks are one of the most terrifying experiences for Windows users. With files locked, screens frozen, and demands for payment flashing on your monitor, it can feel like the end of the road. But here’s the truth: you don’t have to pay to recover. In this guide, we’ll walk you through practical steps to regain control of your PC, eliminate the infection, and restore your files—without spending a single cent.

What Is Ransomware?

Ransomware is malicious software that encrypts your data or locks your system, then demands payment (often in cryptocurrency) for the decryption key or access code. Common ransomware variants include WannaCry, Locky, and STOP/Djvu.

Step 1: Disconnect From the Internet Immediately

The moment you suspect a ransomware infection:

  • Unplug your Ethernet cable

  • Turn off Wi-Fi

This stops the ransomware from communicating with its command and control server, and can prevent further encryption.

Step 2: Enter Safe Mode

  1. Restart your PC.

  2. Hold Shift while selecting Restart.

  3. Choose Troubleshoot > Advanced options > Startup Settings > Restart.

  4. Press F4 to boot into Safe Mode.

Safe Mode loads Windows with only the essential programs, making it easier to isolate and remove malware.

Step 3: Identify the Ransomware Variant

Knowing the exact ransomware strain helps you find the right solution.

  • Take a photo or note of the ransom note.

  • Use online tools like ID Ransomware to upload the note or encrypted files for identification.

Step 4: Remove the Ransomware

Use reputable antivirus tools to scan and remove the malware. Good free options include:

  • Malwarebytes Free

  • Kaspersky Virus Removal Tool

  • Microsoft Defender Offline Scan

Run a full system scan and quarantine or delete any threats found.

Step 5: Try to Restore Files Without Paying

Depending on the ransomware type, you may be able to recover your files for free.

Option A: Use a Free Decryption Tool

Once you know the variant, check if a free decryptor is available at:

Follow instructions carefully—some tools only work for specific versions.

Option B: Restore from Shadow Copies (if available)

Some ransomware doesn't delete Windows shadow copies:

  1. Press Win + R, type cmd, and open as Administrator.

  2. Enter:

    vssadmin list shadows
    
  3. If shadow copies exist, try using ShadowExplorer or:

    Previous Versions > Restore
    

Option C: Restore from Backups

If you use File History, Windows Backup, or an external/cloud backup:

  • Connect your backup drive or log into your cloud account.

  • Restore your files manually.

Option D: Use File Recovery Software

If the ransomware deleted your files instead of encrypting them, try tools like:

  • Recuva

  • PhotoRec

  • EaseUS Data Recovery Free

Note: success depends on whether the sectors of your hard drive have been overwritten.

Step 6: Clean Install Windows (If Needed)

If the damage is too extensive:

  1. Backup any uninfected or decrypted files to a clean external drive.

  2. Download a fresh Windows ISO from Microsoft’s official site.

  3. Create a bootable USB using Rufus or Media Creation Tool.

  4. Reinstall Windows and format your drive during setup.

This gives you a clean start and removes all traces of the ransomware.

Step 7: Harden Your System Against Future Attacks

✅ Tips to Stay Protected:

  • Keep Windows and software updated.

  • Use strong, unique passwords and 2FA.

  • Install a reliable antivirus or endpoint security solution.

  • Enable Controlled Folder Access (Settings > Update & Security > Windows Security > Virus & threat protection).

  • Back up regularly to an offline drive or secure cloud service.

  • Avoid clicking unknown links or downloading suspicious attachments.


Final Thoughts

Ransomware attacks are scary, but not hopeless. With the right tools, quick action, and a methodical approach, you can defeat the attack and recover your files—without rewarding cybercriminals.

Don’t let fear drive you to pay the ransom. Instead, arm yourself with knowledge and take back control of your PC.
