How to decrypt files after CTB-Locker infection?

You may attempt to decrypt files infected by different versions of CTB-Locker manually. Modern ransomware threats use complex encryption algorithms and try to prevent users from decrypting their files by disabling System Restore option, removing Shadow copies and previous versions of user files. However, in most cases, there is still a chance to restore your files using one of the described metods. There is also special advanced data recovery software, that can revive lost data in several clicks. This is not a guarantee for data restoration, but it is worth giving a try.

Using advanced data recovery software

  1. Download and run 'Recuva Professional'
  2. Click on the result
  3. Choose the date before the infection appearance
  4. Follow the on-screen instructions

Restore encrypted files using System Restore

System Restore constantly creates copies of files and folders before major changes in the system (windows update, software installation). You can also create restore point manually from time to time. CTB-Locker may remove system restore files, but you can check it using following instruction.

windows system restore
  1. Click Start and search for 'system restore'
  2. Click System Restore result (Recovery in Windows 10)
  3. Choose any date before the infection appeared
  4. Follow the wizard instructions

Roll the files back to the previous version

Previous versions are copies of files and folders made by Windows Backup (if Windows Backup option is turned on) or copies of files and folders created by System Restore. You can use this feature to restore files and folders that you accidentally modified or deleted, or that were encypted by CTB-Locker. Available only in Windows 7 and later versions.

windows previous versions of files
  1. Right-click on the file and select Properties
  2. Click on the Previous Version tab
  3. Choose the latest version and click Copy
  4. Finally, click Restore

Restore files using shadow copies

shadow explorer
  1. Download Shadow Explorer and run it.
  2. Choose the drive and the folder, where encrypted files are located and date, when they were in normal state.
  3. Right-click on the folder, that you want to restore and choose Export.
  4. Select location folder for export and overview restored files.

Protect your computer from ransomware

Most of modern antivirus solutions have a module to protect from ransomware threats. However, there are also special solutions, that can detect cryptoviral activity and stop it, preventing modification of your files. One of the best is ZoneAlarm Anti-Ransomware utility, that will not use much resources for effective protection against latest ransomware threats.

zonealarm anti-ransomware
  1. Download and run ZoneAlarm Anti-Ransomware.
  2. Install it (works only on Windows).
  3. You are protected from encryption activity.
