What is a DJVU file?

A DJVU file is a scanned document saved in the DjVu image format. It may contain text, images, and/or drawings. The DjVu format was developed by AT&T and marketed by LizardTech.

DJVU (pronounced "deja vu") files are very similar to .PDF files. Using DJVU creators, users can scan high-resolution color pages of books, magazines, comics, catalogs, and other documents and publish them on the web. Many DJVU files contain ebooks, archived and published by book digitization projects.

AT&T Labs published the initial version of the DJVU format in 1998. The format was most recently revised in 2005. Before Adobe standardized the PDF format in 2008, DJVU was considered the superior document format. Notably, DJVU is open source, and it can compress documents to smaller sizes than .JPEG, .GIF, and .TIFF compression.

You can open a DJVU file in many document viewing applications. Some, like WinDjView, MacDJview, and DjVuLibre DjView, are designed specifically to open DJVU files. Others, like Calibre, Sumatra PDF, and KDE Okular, can open many types of documents.

STOP DJVU Ransomware Encrypted File

In rare cases, a DJVU file may be a file that has been encrypted and renamed by STOP Djvu ransomware, which is malware distributed by cybercriminals. It contains a file, such as a .DOCX, .XLSX, .JPG, or .PNG file, that has been encrypted and renamed by the virus. Users whose PCs have been infected by STOP Djvu can attempt to decrypt their DJVU files using Emsisoft Decryptor for STOP Djvu.

More Information

STOP Djvu ransomware is one of the most commonly distributed types of ransomware. After STOP Djvu infects a user's computer and encrypts their files, it produces a ransom message named _readme.txt. The message contains instructions a user is supposed to follow to decrypt their files.

Typically, the ransom message asks for a ransom of $980, unless the user contacts the ransomer in the first 72 hours after infection, in which case the ransom is halved to $490. Other variants of STOP ransomware append users' files with the .STOP, .rumba, .radman, .gero, or .CADQ extensions.

How did my computer get infected by STOP Djvu ransomware?

STOP Djvu ransomware is most commonly distributed in programs that appear to be legitimate but are actually adware and malware bundles. If you recently downloaded and installed an unverified program, that may be how STOP Djvu ransomware infected your computer.

How to open a DJVU file

DJVU files are encrypted and cannot be opened. If you want to attempt to decrypt your DJVU files and return them to their pre-infected state, you can use Emsisoft Decryptor for STOP Djvu. The decryptor's website includes detailed instructions for decrypting DJVU files.

Warning

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.
