Vvoa ransomware – a new variant of the ever-expanding Djvu family

Vvoa ransomware virusVvoa ransomware - cryptovirus that makes data inaccessible and asks for payments.

Vvoa ransomware is a computer virus that locks victim files until a ransom is paid. The cryptovirus derives from the wicked Djvu ransom family. First detected in 2016, this family keeps on growing. To this day there are more than 250 versions and there's no telling when will it stop. Viruses from this family typically use an army-based RSA[1] algorithm for encryption. Previous versions were decryptable, but recent years show activities of non-decryptable malware that uses on powerful encoding methods and online IDs while locking files. Those include Iiss, Agho, Jdyi.

As soon as Vvoa ransomware virus lands on a targeted device it starts the encryption process immediately, after that's done all files are inaccessible and renamed – a .vvoa extension is appended. Subsequently, a ransom note named _readme.txt is created in all affected folders. Developers of the virus in the said note tell their victims what happened to their devices and what needs to be done to get their files back.

MAlware removal To remove Vvoa ransomware use a trustworthy anti-malware software
System fix Once Vvoa virus removal is completed, it is highly recommended using the ReimageIntego tool to get your device back in shape

The creators of Vvoa ransomwareare kind enough and offer to send them one file from the infected computer. They would send a decrypted file back, thus proving that the decryption tool really exists and that they have it. Furthermore, they are enclosing a link to a video to see the decryption in action. The ransom amount is 480 USD but only if the victims contact the criminals within 72 hours, if not the price is doubled to 960 USD. 

However tempting it might be to pay the criminals and retrieve your files, the FBI warns[2] that such action doesn't guarantee that you will receive the promised tool, and additionally increases criminal's motivation to expand their attacks and create more sophisticated malware than Vvoa file virus.

We recommend to remove Vvoa ransomware automatically using SpyHunter 5Combo Cleaner or Malwarebytes anti-malware applications. These are trustworthy programs that will safeguard your future browsing experiences if you update their virus databases regularly.

Your personal ID

Difference between offline and online IDs that affects .vvoa file decryption

It is known that since August 2019, Djvu family is not using offline IDs, in most cases. These victim IDs or decryption keys are used when a particular set of numbers get generated during the file-locking procedure. Previously helpful decryption tools relied on offline keys and made victims happy when most of their data got recovered easily. Vvoa ransomware got released in November 2020 – it is not decryptable.

Online IDs are unique for each victim, so even when researchers obtain one decryption key – there is no way to recover other data. Decryption keys received from virus developers' can work for only one machine and those files affected on the computer. You need to either risk and pay Vvoa virus creators for the key or go for other methods.

Decryption tool development takes time. Other ways to obtain such decryption keys without paying criminals is to wait for the official file recovery program or law enforcement actions. It takes even longer. We recommend removing Vvoa file virus with anti-malware tools and recovering files yourself or with the help of third-party tools, PC options. 

File recovery after Vvoa ransomware infection

Having your files locked is a nightmare. That being said, contacting the criminals, or even worse – paying the ransom isn't the only solution. Unfortunately, deleting the malware won't unlock your Vvoa virus files, but we're here to help. 

The first solution after your device is virus-free and you've done the whole system checkup routine, mentioned in the paragraph below, is to restore your files from backups. If you didn't keep backups, transfer all virus affected .vvoa files to offline storage and either use one of our suggested recovery methods below this article or wait for a public decryption key to be available.

Another method to remove .vvoa extension from your files is using Emisoft created decryption tools. They specialize in such software and constantly updates their product. So if there's no decryptor available now, you should either check back with them or with us to see any updates on this matter.

Other techniques are described at the bottom of this article and require your attention to details. Remember to terminate Vvoa ransomware before any data recovery options. Emsisoft's decrypter or media file repair tool can work for some of the files, but not always.

System restore and Vvoa ransomware removal

99% of Djvu family ransomware is distributed by illegal activations toolkits for licensed software (aka cracks) and other files on torrent websites. Please refrain from using those sites. Support the developers of your desired programs by buying them directly from official websites.

Users should always have their backs watched by trustworthy anti-malware software. We recommend using reliable anti-malware apps like SpyHunter 5Combo Cleaner or Malwarebytes to remove Vvoa ransomware from infected devices automatically. These apps will locate, isolate, and delete the computer virus and all its allocated files spread out through the device.

As good as anti-virus software is at detecting and removing infections, it can't fix registry and other system files and settings. To restore your computer to a pre-contaminated phase use the ReimageIntego tool. It will automatically find and restore whatever the Vvoa ransomware virus has done to system-related settings/files.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Vvoa from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Vvoa, you can use several methods to restore them:

Data Recovery Pro is a professional file restoring tool

Data Recovery Pro might be a good app to try and recover your files after Vvoa ransomware attack

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Vvoa ransomware;
  • Restore them.

Try Windows Previous Version feature – solution for data restoring

Windows Previous Version feature might also be useful, although you would have to restore one file at a time

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

File recovery using ShadowExplorer

If all other methods, described above, didn't work, try using ShadowExplorer to find lost versions of your data

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Decryption tool can posisbly help

Djvu decrypter can be used in some cases

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Vvoa and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
