.DJVU File Extension

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.

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.

You can use Calibre, Sumatra PDF, or DjVu Converter to convert DJVU files to other formats. For example, Calibre can convert DJVU files to the following formats (and several others):

• .EPUB - Open eBook
• .AZW3 - Amazon KF8 eBook
• .MOBI - Mobipocket eBook
• .DOCX - Microsoft Word Document
• .FB2 - FictionBook 2.0
• .HTMLZ - Zipped HTML eBook
• .LIT - Microsoft LIT eBook
• .PDF - Portable Document Format
• .TXT - Plain Text
• .RTF - Rich Text Format

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.

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.

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.
