What is a KCXZ file?

A file with the .kcxz extension has been renamed and encrypted by KCXZ ransomware. It contains an image, document, or other file the ransomware is holding hostage. The .kcxz extension is appended to the file's normal extension, producing a compound extension like .jpg.kcxz.

More Information

Like other forms of ransomware, KCXZ ransomware encrypts a user's files and then produces a plain text ransom note. The note contains instructions users can supposedly follow to purchase a decryption key and restore their files.

Infected files' names gain not only the .kcxz extension, but also the word locked at the beginning of their name. Thus, an infected file named example001.jpg would become locked-example001.jpg.kcxz.

How to open a KCXZ file

No known program can restore KCXZ files to their original state. The best way to recover your files is to retrieve them from a recent backup or perform a System Restore to a point before your computer was infected.


FileInfo.com recommends you never pay a ransom to decrypt files encrypted by ransomware. Paying a ransom encourages ransomware distributors to continue their efforts, and there is no guarantee that paying a ransom will give you access to your files. Instead, you should restore your data from a recent backup created before the ransomware infected your computer.
