What Is Yoqs Virus?
Yoqs virus is the type of malware, that is commonly referred to as a ransomware infection. This virus is part of a large scale operation, also known as the Djvu crypto-virus family. Its primary purpose is to get in your computer undetected and attack your important files. This virus encrypts all the important files, making them no longer openable and leaves behind a ransom note, that is called _readme.txt. This note asks the victim to be hundreds of dollars in the form of bitcoin so that he or she can get a decryption key from the criminals and use it to decrypt .yoqs files.
Read this article in order to learn more information on how this virus got into your computer in the first place, how does it work and how you can remove it and try to decrypt your files for free.

Yoqs Virus – How Did I Get Infected?
Just like the latest Djvu viruses, from which are the Zaqi, Luez and Yber variants, the Yoqs virus may also get inside your computer by being sent to you as an email attachment that poses as important document, for example:
- Work-related files.
- Receipts.
- Invoices.
- E-Tickets for events or flights.
Yoqs virus may infect you in the following order as soon as you download and run this attachment:
Another way that has been reported to infect victims with the Djvu viruses is by downloading some type of executable file, that pretends to be a patch, hack tool or a crack. If this is the case, then the files could likely be hosted on some low reputation website and could be of the following types:
- Self extracting archives or regular archives.
- Fake installation files.
- Software patches.
- Cracked portable versions of apps.
- Software or game cracks.
- Key generator (or Keygen).
Yoqs Virus – What Does It Do?
Yoqs virus first connects to a remote server from where it downloads the malicious files that it uses to encrypt your important data. These “module” files often are more than 3 and they could be located in the following directories of Windows:
- %Windows%
- %SystemDrive%
- %LocalLow%
- %AppData%
- %Local%
- %Temp%
- %System%
- %system32%
The virus then creates a custom ransom note, specifically designed for your computer to identify that it is the one being infected. This note is called _readme.txt and usually has the following extortionist message:
The Windows Registry Editor may also be attacked by the Yoqs virus as it aims to create entries in the “Run” and “RunOnce” keys:
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
What Are .yoqs Files
Yoqs files virus may use AES encryption algorithm to encrypt your important files and add the .yoqs file extension after each file. The files that are encrypted are usually the following:
- Audio (.mp3, .wav, etc.).
- Picture file kinds (.jpg, .png, .etc).
- Videos (.mp4, .avi, etc.).
- Archive file formats (.zip, .rar, etc).
- Documents of different types (.docx, .pptx, etc.).
- Others.
After the encryption process has completed, this malware may leave the files appearing like the following:

Step 2: Uninstall Yoqs and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Step 3: Clean any registries, created by Yoqs on your computer.
The usually targeted registries of Windows machines are the following:
- 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
You can access them by opening the Windows registry editor and deleting any values, created by Yoqs there. This can happen by following the steps underneath:
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Yoqs
Step 5: Try to Restore Files Encrypted by Yoqs.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
