.uudjvu Files Virus – How to Remove It

This blog post has been made with the main purpose in order to explain how you can remove the .uudjvu files virus from your computer and how to try and restore data encoded by it.

Yet another instance of the DJVU ransomware virus has just appeared. The ransomware seems to carry the .uudjvu file extension appended to the files encrypted by it. The virus aims to encode the files on the computers attacked by it and then set the .uudjvu file extension to the encrypted files as a suffix. The virus reportedly uses RSA and AES encryption to perform its encryption. It then drops a ransom note, called “_openme.txt” and it contains ransom instructions on how the victim can pay a hefty ransom in order to retrieve his or her files back to normal. If your computer was just attacked by the .uudjvu files virus, we would strongly suggest that you read this article thoroughly.

.uudjvu Files Virus – How Does It Infect

The primary infection method used by the creators of this ransomware virus is allegedly malicious e-mails that contain attachments which are actually infection files. This technique also known as malspam is used by cyber-criminals to deceive users that they have received an important e-mail attachment, like a document from a bank, an invoice, a receipt or even something more personal, like a notice that they are being fired from their job. All of this is done with the goal to get the victims to open the attachment and once this is done, the .uudjvu files virus may begin it’s infection process.

Furthermore, in addition to infecting computers via malspam, the .uudjvu files virus may also perform infection via various different types of files that are uploaded on the web. These files may be programs that users tend to download online and often turn out to be:

  • Portable versions of programs.
  • Activators.
  • Cracks.
  • Patches.
  • Key Generators.
  • Drivers.

The files are actually infection files, whose main purpose is to get users to activate them and trigger a Trojan.Dropper or a Trojan.Downloader who drop the payload of .uudjvu files virus on the infected computer system.

.uudjvu Files Virus – More Information

In addition to the ransom note of .uudjvu ransomware, the virus may also connect to the server of the cyber-cyber-criminals who are actually behind it in order to relay information about the infected computer, such as:



  • IP address.
  • Location.
  • Network configuration.
  • Passwords.
  • Content of files.
Take Screenshots from the desktop.
  • Change network settings.

Then, the .uudjvu files virus may continue with it’s malicious activities and go ahead and delete the shadow volume copies of the infected computer. This is done with the main goal of eliminating the possibility for users to recover their files via Windows Recovery options. To reach their end goal, the crooks may have devised a script that deletes these copies by running administrator commands in Windows Command Prompt, some of which may be among the list of commands below:

→ sc stop VVS
sc stop wscsvc
sc stop WinDefend
sc stop wuauserv
sc stop BITS
sc stop ERSvc
sc stop WerSvc
cmd.exe /C bcdedit /set {default} recoveryenabled No
cmd.exe /C bcdedit /set {default} bootstatuspolicy ignoreallfailures
C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet

And to get the virus file of the .uudjvu files virus to run automatically when you start Windows, the ransomware may also set registry entries in the following sub-keys, which could contain the actual location of the module, responsible for encryption:

→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

.uudjvu Files Virus – How Does It Encrypt

In order to render your files temporary obsolete, the .uudjvu files virus may set various different types of procedures in place. One of them is to scan for the commonly used files on your computer and detect and encrypt them based on their file extension. The most commonly encrypted file extensions are usually among the ones below:

→ “PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML.

After the .uudjvu files virus detects the files on the infected machine that are eligible for encryption, the malware may use one or more of the following encryption algorithms in order to encode files:

  • AES-256
  • RSA-2048
  • Salsa20

The encryption can be done in more than one way, whereas the most common method is to copy the original file and then encrypt the copy by altering data segments from it with the encryption algorithm, enough to make it obsolete. After the encryption is done, the .uudjvu files virus may delete the original files and leave only the encrypted ones, looking, like the example below shows:

→ New Microsoft Word Document.docx.uudjvu
