A ransomware attack might lock your files and demand payment for their release. Not advised is paying the ransom since file recovery is not guaranteed. Rather, using correct procedures will help to secure your system and enable access to your data. This tutorial offers detailed, methodical instructions for properly recovering from a ransomware infestation.
Common Signs of a Ransomware Attack
- Locked or Encrypted Files – You cannot open your documents, images, or software.
- Ransom Note Displayed – A message demands payment for file recovery.
- Unusual File Extensions – Your files are renamed with unknown extensions (e.g., .locked, .crypt).
- Slow System Performance – Ransomware runs in the background, using system resources.
- Disabled Security Features – Windows Defender or antivirus software is turned off.

Disconnect from the Internet Immediately
Unplug Ethernet cables or turn off Wi-Fi to prevent further data encryption.

Restore Files from Backup
If you have backups stored offline or in the cloud, restore your system from a clean backup.
Do not restore from infected storage devices.
Use Windows File History or System Restore
Open Control Panel -> File History -> Restore Personal Files.
Alternatively, use Control Panel -> Recovery -> Open System Restore to revert to an earlier state.
Scan and Remove the Ransomware
Boot into Safe Mode (Shift Restart → Troubleshoot -> Advanced options -> Startup Settings -> Safe Mode).
Run a full scan using Windows Defender, Malwarebytes, or another trusted antivirus.
Remove any detected threats.
Check for Shadow Copies (For Older Windows Versions)
Open Command Prompt as Administrator and type:
vssadmin list shadows
Reinstall Windows if Necessary
If ransomware has deeply infected your system, reinstall Windows.
Ensure all personal files are backed up before proceeding.
Strengthen System Security to Prevent Future Attacks
