What is a ZZZZZ file?

A ZZZZZ file is a file encrypted by Locky ransomware, a virus utilized by cybercriminals. It contains a user's personal file, such as a .TXT or .PNG file, encrypted with AES-265 and RSA methods. ZZZZZ files became popular in 2016.

More Information

The Locky virus is highly dangerous malware. It is commonly referred to as ransomware, where the purpose of the virus is to take your files hostage and force you to pay the perpetrator (by way of bitcoin) to unlock your files. The virus is a trojan horse that is spread via spam emails that include infected attachments or malicious links. Once the virus affects your computer it begins scrambling your files, renaming them, and encrypting them. The virus then generates a .TXT ransom note informing you of the takeover and what you need to do to recover your files.

How to open a ZZZZZ file

No program can currently restore ZZZZZ files to their original state. The best option for retrieving your files is likely to recover them from a recent backup.


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.
