Vvwq virus – what is it?
Vvwq malware can correctly be described as a STOP/Djvu malware family. That type of computer virus is targeted at individuals. This specification supposes that Vvwq does not carry any type of additional malware, which often helps virus of various other families to control your PC. Since most users do not have anything valuable on their PCs, there is no need to inject other viruses that increases the risk of failure of the whole ransomware operation.
The common signs of Vvwq ransomware activity is the emersion of .vvwq files in your folders, instead of the document you used to have. The photo.jpg turns into photo.jpg.vvwq, report.xlsx – into report.xlsx.vvwq and so on. You are not able to suspend this action, as well as can’t open these documents – they are ciphered with quite strong cipher.
You can also see various other signs of malware activity. Suddenly blocked Microsoft Defender and inability to open the famous anti-malware forums or web pages, where the ransomware removal and decryption guides are posted. You will see how it is conducted in the paragraph below. The removal and decryption guide are also available – check below how to remove Vvwq ransomware and get the .vvwq files back.
How did Vvwq ransomware encrypt my files?
After the malware injection, the Vvwq virus starts a connection with its command and control server. This server is controlled by malware maintainers – people who manage the spreading of this virus. Another activity which is conducted by these crooks is answering the email messages of victims, who wish to decrypt their files.
The documents are ciphered with one of the strongest encryption algorithm – AES-256. The digit in the name of this algorithms means the power of two – 2^256 for this case. 78-digit number of possible decryption keys variations – it is unreal to brute force it. As cipher analysts say, it will take more time than the Earth can approximately exist, even in case if you use the most powerful computers. In each folder that contains the encrypted documents, Vvwq virus leaves the _readme.txt file with the following contents:

Nonetheless, you can still run some of your files. The Vvwq ransomware encrypts only the initial 150 KB of each file, but the rest of this file can be opened. Primarily, it works best with audio/video files, which are surely larger than 150 kilobytes. Not each media player is capable of open these files – WinAmp is the best choice, since it is free and well-tested. First seconds of each recording will be missing – this part is encrypted – but the rest of the file will be accessible like nothing happened.
Is Vvwq ransomware dangerous for my PC?
As it was described several paragraphs before, ransomware is not only about ciphering the files. Vvwq virus makes the changes in your OS in order to prevent searching the malware removal and file decryption guides. Vvwq virus does not create the software obstacle – it just alters the settings, primarily – networking and security configurations.
Among the networking settings, the most changed item is the HOSTS configuration file. This text file keeps the DNS-address instructions, which are used by the browsers while requesting to the server. If you add a specific DNS-address for the certain website, your browser will connect that site through that DNS next time. Ransomware edits this file, adding the non-existent DNS, so any of the web browsers will show you the “Unable to resolve the DNS-address” error.
Other alterations done by the ransomware are aimed at prevention of operative detection of itself, and also disabling the installation of the majority of antivirus programs. Vvwq virus implements several alterations in Group Policies – the system configuration app which gives you the right to change the abilities of each program. In such a way, the virus blocks the Microsoft Defender and different other security apps, as well as blocks the launch of anti-malware installation files.
How did I get infected?
Throughout the whole term while STOP/Djvu family is active, it was using dubious applications as a primary method of ransomware injection. Under the term of dubious software I mean applications that are already not controlled by the developer and distributed through the third-party websites. These applications may be hacked, to make them possible to use without purchasing any license. One more example of such a program class is various hacking tools – cheat engines, keygens, Windows activation tools and so on.
Such programs may be distributed in many ways – through the web page that offers a downloading link, or through the peering networks – ThePirateBay, eMule and so on. All these sources are known as the most popular computer piracy resources. People use these pages to get various apps or games for free, even if these apps must be purchased. No one can stop the users who hack these apps from adding viruses of some sort to the files of the hacked tool. Hacktools, however, are created for outlaw actions, so their creators may easily embed the ransomware under the guise of some program element.
These hacked apps, regardless of their source, are one of the most often sources for various viruses, and surely the most used one for Vvwq malware. It is better to avoid making use of it, and not only because of malware injection risks. Avoiding the license buying is an outlaw action, and both hackers and users who make use of cracked programs fall under the charge of piracy.
How do I remove Vvwq ransomware?
The Vvwq malware is really hard to remove manually. In fact, because of the number of changes it makes in your computer, it is almost impossible to find them all and fix. The best decision is to make use of anti-malware software. But which one to choose?
You may see the advices to make use of Microsoft Defender, which is already inside of your Windows. Nonetheless, as it was mentioned earlier, most of STOP/Djvu virus examples disable it even before the ciphering process. Using the third-party tool is the only solution – and I can advice you the GridinSoft Anti-Malware as an option for that case. It has impressive detection abilities, so the Vvwq ransomware will not be missed. It is also capable of system recovery, that is heavily demanded after the Vvwq virus attack.
To remove Vvwq malware infections, scan your computer with legitimate antivirus software.
After the ransomware removal, you can go to file decryption. Ransomware removal is required to prevent the repeating encryption of your files: while Vvwq ransomware is active, it will not pass any unencrypted file.
How to decrypt the .vvwq files?
There are two ways to decrypt your files after a Vvwq malware attack. First one and the most popular is file decryption. It is performed with a special app, designed by Emsisoft, and named Emsisoft Decryptor for STOP/Djvu. This program is free. Analysts update its decryption keys databases as often as possible, so you will definitely get your files back, sooner or later.
Another way to get your files back is to try to recover them from your disk drives. Since Vvwq virus deletes them and substitutes with a ciphered copy, the residue of the documents are still kept on the disk. After the deletion, the information about them is removed from the file system, but not from a disk. Special programs, like PhotoRec, are able to recover these files. It is free, too, and may also be used for file recovery in case when you have deleted some files unintentionally.
Decrypting the .vvwq files with Emsisoft Decrypter for STOP/Djvu
Download and install Emsisoft Decrypter tool. Agree with its EULA and continue to the interface.
The interface of this program is extremely easy. All you have to do is to select the folder where the encrypted files are stored, and wait. If the program has the decryption key which corresponds to your ransomware case – it will decrypt it.
During the use of Emsisoft Decrypter for STOP/Djvu, you may observe various error messages. Don’t worry, that does not mean that you did something wrong or a program does not work properly. Each of these errors refer to a specific case. Here is the explanation:
Error: Unable to decrypt file with ID: [your ID]
The program does not have a corresponding key for your case. You need to wait for some time until the key database will be updated.
No key for new variant online ID: [your ID]
Notice: this ID appears to be an online ID, decryption is impossible.
This error means that your files are encrypted with an online key. In such a case, the decryption key is unique and stored on the remote server, controlled by crooks. Unfortunately, the decryption is impossible.
Result: No key for new variant offline ID: [example ID]
This ID appears to be an offline ID. Decryption may be possible in the future.
Ransomware uses the offline key to encrypt your files. This key is not unique, so you likely have it in common with another victim. Since offline keys must be collected, too, it is important to keep calm and wait until the analysts team finds one which will fit your case.
Remote name could not be resolved
This error indicates that the program has problems with DNS on your computer. That’s a clear sign of malicious alterations in your HOSTS file. Reset it using the official Microsoft guide.
Recovering the .vvwq files with PhotoRec tool
PhotoRec is an open-source tool, which is created to recover the deleted or lost files from the disk. It checks each disk sector for the residues of deleted files, and then tries to recover them. That app is able to recover the files of more than 400 different extensions. Because of the described feature of ransomware encryption mechanism, it is possible to use this tool to get the original, unencrypted files back.
Download PhotoRec from the official website. It is absolutely free, however, its developer warns that he does not guarantee that this program will be 100% effective for file recovery purposes. Moreover, even paid apps can barely give you such a guarantee, because of the chain of random factors that can make the file recovery harder.
Unzip the downloaded archive to the folder you like. Don’t worry because of its name – TestDisk – this is the name of the utility developed by the same company. They decided to spread it together since PhotoRec and TestDisk are often used together. Among the unzipped files, search for qphotorec_win.exe file. Run this executable file.
Before you can start the recovery process, you need to specify several settings. In the drop-down list, choose the logic disk where the files were stored before the encryption.
Then, you need to specify the file formats you need to recover. It may be difficult to scroll all 400+ formats, luckily, they are sorted by alphabetical order.
Finally, name the folder you want to use as a container for recovered files. The program will likely dig out a lot of useless files, which were deleted intentionally, so desktop is a bad solution. The best option is to use the USB-drive.
After these easy manipulations, you may just press the “Search” button (it turns active if you specified all required parameters). The recovery process may take several hours, so keep patient. It is recommended not to use the computer during this term, since you may overwrite some files you are intending to recover.
Frequently Asked Questions
✔️Are the files encrypted by Vvwq malware dangerous?
No. Vvwq files is not a virus, it is not able to inject its code into the files and force them to execute it. The .EXT files are just the same as regular ones, but encrypted and cannot be opened in the usual way. You may store it together with normal files without any fears.
✔️Is it possible that antivirus software will delete the encrypted files?
As I have mentioned in a previous paragraph, encrypted files are not dangerous. Hence, good anti-malware programs like GridinSoft Anti-Malware will not trigger on them. Meanwhile, some of the “disk cleaning tools” may remove them, stating that they belong to the unknown format and are likely broken.
✔️The Emsisoft tool says my files are encrypted with the online key and cannot be decrypted. What do I need to do?
It is very unpleasant to hear that the files you have are likely lost. Ransomware creators lie a lot in order to scare their victims, but they tell the truth in claims about the strength of the encryption. Your decryption key is stored on their servers, and it is impossible to select it because of the strength of the encryption mechanism.
Try other recovery methods – through the PhotoRec, or using the previously created backups. Search for the previous versions of these files – getting back a part of your dissertation, for example, is better than missing it all.
Last option is just waiting. When the cyber police caughts the crooks who create and distribute ransomware, first get the decryption keys and publish it. Emsisoft analysts will surely take these keys and add them to the Decryptor databases. In some cases, malware creators may publish the rest of the keys when they stop their activity.
✔️Not all of my .vvwq files are decrypted. What do I need to do?
The situation when the Emsisoft Decryptor failed to decrypt several files usually happens when you have not added the correct file pair for the certain file format. Another case when this problem may appear is when some problem occurred during the decryption process – for example, RAM limit reached. Try to perform the decryption process once again.
Another situation when the Decryptor app may leave your files unencrypted is when ransomware uses different keys for certain files. For example, it may use offline keys for a short period of time when it has connection issues. The Emsisoft tool is not able to check both key types simultaneously, so you need to launch the decryption again, in order to repeat the process.
