Ransomware attacks are one of the fastest-growing cybersecurity threats. In 2024 alone, global ransomware damages were estimated to exceed $30 billion, with businesses and individuals alike falling victim. The consequences are devastating: encrypted files, locked systems, and ransom demands in cryptocurrency.

If you’re using Windows 10 and suspect your system has been compromised, don’t panic. This guide explains how to remove ransomware in Windows 10, recover encrypted files, and strengthen defenses to prevent future attacks.

What is Ransomware and How Does it Work?

Ransomware is malicious software designed to block access to your files or system until a ransom is paid. Attackers typically demand payment in Bitcoin or other cryptocurrencies to provide a decryption key.

Common Types of Ransomware

  • Crypto ransomware – Encrypts files and demands payment for decryption.

  • Locker ransomware – Locks the screen and prevents access to the device.

  • Scareware – Displays fake alerts or warnings to trick users into paying.

Ransomware often infiltrates Windows 10 systems through:

  • Phishing emails with malicious attachments.

  • Malicious software downloads or cracked programs.

  • Drive-by attacks on compromised websites.

Signs Your Windows 10 PC is Infected with Ransomware

How do you know if ransomware has taken over your system? Look for these telltale signs:

  • Files suddenly have strange extensions like .locked, .encrypted, or .payme.

  • You see ransom notes or warning messages demanding payment.

  • The screen is locked with a message from attackers.

  • System performance slows down drastically.

  • Security tools are disabled without your input.

If you notice these symptoms, take immediate action before the ransomware spreads further.

Immediate Steps to Take When You Suspect Ransomware

  1. Disconnect from the Internet – Prevent the malware from communicating with its command-and-control servers.

  2. Do Not Pay the Ransom – Payment doesn’t guarantee recovery and encourages further attacks.

  3. Boot into Safe Mode – Limits active processes, making removal easier.

  4. Identify the Ransomware Strain – Check ransom notes, file extensions, or use tools like ID Ransomware.

How to Remove Ransomware in Windows 10

Method 1: Use Windows Security (Built-in Defender)

Windows 10 comes with a capable built-in antivirus called Windows Security (Defender).

  • Open Settings → Update & Security → Windows Security.

  • Run a Full Scan.

  • Quarantine or remove detected threats.

Method 2: Remove Ransomware with Safe Mode and System Restore

  • Restart your PC and press F8/Shift+Restart → Select Safe Mode.

  • Navigate to Control Panel → Recovery → System Restore.

  • Select a restore point before the infection occurred.

This won’t always decrypt files but can remove the malicious software.

Method 3: Use Specialized Anti-Ransomware Tools

Several third-party tools are highly effective:

  • Malwarebytes Anti-Ransomware

  • HitmanPro.Alert

  • Kaspersky Anti-Ransomware Tool

Steps:

  1. Download tool from official site (on a clean device if needed).

  2. Install and run a deep system scan.

  3. Remove detected ransomware and restart your PC.

Method 4: Manual Removal (Advanced Users)

For professionals, manual removal may be an option:

  • Open Task Manager (Ctrl+Shift+Esc) → End suspicious processes.

  • Navigate to C:\Users[Username]\AppData\Local or Temp to delete suspicious files.

  • Use Regedit to check for malicious startup entries.

⚠️ Warning: Manual removal is risky and may damage the system if done incorrectly. Use only if you’re experienced.

How to Recover Encrypted Files After Ransomware

Even after removing ransomware, your files may still be encrypted. Here’s what you can do:

  • Check if the ransomware is decryptable via resources like NoMoreRansom.org.

  • Restore from Backups – Use local or cloud backups created before infection.

  • Windows File History or Shadow Copies – Right-click the file → Properties → Previous Versions.

If backups exist, restoring is the safest method to regain access.

Best Practices to Prevent Ransomware in Windows 10

Prevention is more effective than recovery. Follow these steps to protect your system:

  1. Regular Backups – Store copies offline or in the cloud.

  2. Update Windows & Software – Patch vulnerabilities quickly.

  3. Use Strong Passwords + MFA – Prevent unauthorized access.

  4. Be Cautious with Emails – Don’t click unknown links or attachments.

  5. Install Reliable Antivirus & Firewall – Keep active real-time protection.

  6. Limit Admin Privileges – Avoid giving unnecessary permissions.
