Dqws Virus – How Did I Get Infected?

Dqws virus is very approximate to some other versions of this family, including the recently detected .hajd, .qall and .ghas ones.

The Dqws virus may cause an infection of your computer system via one of the following methods:

  • If downloaded from some shady third-party software download site.
  • If you have received it in the form of an e-mail attachment or a URL in your e-mail inbox.

If the Dqws virus is sent to you in the form of an email attachment, there is a chance that it could pretend to be one of the following types of files:

  • Invoice files.
  • Receipt documents.
  • Work-related documents.
  • E-Tickets of some kind (flights, train, events).

If this is the case and the file is indeed a document, and it may contain a malicious macro called that may trigger the following infection process once you download and run the file and enable its contents:

Another way you can get your computer compromised by this infection is through multiple different downloaded files from some shady sites, like:

  • Patches for programs or games.
  • SFX (self extracting) or regular archive files.
  • Cracked applications or portable apps.
  • Crack-fixes or activators for software or games.
  • Keyegens or key generators.

Dqws Virus – What Does It Do?

As soon as an infection has occurred with the Dqws virus, it may connect to a remote server, from where it may silently initiate a download of its payload files and module objects. These files may be located in different Windows directories under different names, like the following folders:

  • %SystemDrive%
  • %Local%
  • %LocalLow%
  • %AppData%
  • %Windows%
  • %Temp%
  • %System%
  • %system32%

The virus, also makes sure that it leaves behind its ransom note, that is called _readme.txt and has the following extortionist message:

STOP ransomware virus ransom message

Not just this but Dqws ransomware may also create value entries in the Windows Registry Editor, targeting the following sub-keys:

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

What Are .Dqws Files

The .Dqws files are basically the encrypted copies of your original files and they are encoded using a sophisticated algorithm, that is also known as AES Encryption. This algorithm changes the structure of the files and makes them no longer able to be opened. What the virus does is it initiates a scan of all of your files and encrypt only the ones that you use the most, while scanning them based on their file extensions, for example:

  • Files that are archives (.zip, .rar, etc).
  • Various sorts of documents (.docx, .pptx, etc.).
  • Audio file formats (.mp3, .wav, etc.).
  • Different picture file types (.jpg, .png, .etc).
  • Video file formats (.mp4, .avi, etc.).
  • Other files.

After it has succeeded in encoding in your files, the virus leaves behind its own extension, making the files appear like the following example shows:
