Angry Duck Ransomware - How To Remove?


Angry Duck crypto-ransomware virus is not an experience that could inspire you. It is quite the opposite: it can diminish your will and convince you to pay an enormous settlement fee. Most of the viruses from this group are greedy and they demand sums that could be used for various other goals. Surprisingly, Angry Duck steps out of its pond, shakes his feathers and starts demanding 10 BTC. Yes, you have read right. Crooks have certainly outdone themselves by attempting to collect such gigantic sum. If 10 Bitcoins does not sound that much: it is approximately 6470.90 US dollars. You can clearly see that money like that is not easy to posses: ordinary people can only dream of paying it. You have no reason to give in to the hackers of Angry Duck virus. If your files are appended with an .adk extension and no longer can be ran, if your screen features a picture seen below, then it is possible that this sneaky waterbird swam into your device.

About Angry Duck Ransomware

Despite its peculiar name, Angry Duck virus is not here to entertain you. Its mission is clear-cut: it will infiltrate into your device and encrypt your files. As the ransom note indicates, this specific variant chose to proceed with AES-512 and RSA-64 FIPS grad encryption. This statement sounds quite bizarre since no other our detected virus (that we can recall) exploited encryption with these ciphers. We are unsure whether it is actually appropriate to go with them for encryption. Anyway, you can download the payload of Angry Duck virus from various places: it can be hiding in social networking sites or email inboxes. It is very likely that you won’t even be aware of the fact that you are infected in the first place. Ransomware viruses always find a way to remain discreet about their existence. That is, until the encryption has been victorious and all of your files were forced to welcome an additional extension: .adk. To make this triumph possible, Angry Duck virus has to deal with small details like changing Windows Registry Keys, finding files that are suitable for encryption. One of the most important features is to stay on a stealthy mode and keep the infected victim unaware of the situation, happening under his nose.


After Angry Duck virus manages to end the encoding process, it is prepared to reveal its identity and instructions for the victim. As we found out, ransomware will change desktop backgrounds to a new image: a fierce duck in a dark setting. It is notable that the same short ransom note is repeated through out the picture for about four times.

If you receive a message that you were not expecting, then it is possible that you are being targeted. These emails can claim to be authorities of airlines, booking facilities and etc. Never open such letters or go to the links that they promote.

In the meantime, you can try universal file-restoring programs that might help. Some tips for the future should also be mentioned. For instance, the fact that your valuable data should be stored in backup storages or kept in USB flash drives. This small decision can save you from having to deal with a ransomware virus. If you get infected, you simply use an anti-malware tool and remove the infection. You won’t need decryption because you will be able to retrieve your files from storages.

Step 3. Restore Angry Duck ransomware affected files using Shadow Volume Copies

If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually Angry Duck ransomware tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so.

Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer.

a) Native Windows Previous Versions

Right-click on an encrypted file and select PropertiesPrevious versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.

It is a program that can be found online for free. You can download either a full or a portable version of Shadow Explorer. Open the program. On the left top corner select the drive where the file you are looking for is a stored. You will see all folders on that drive. To retrieve a whole folder, right-click on it and select “Export”.

Step 4. Use Data Recovery programs to recover Angry Duck ransomware encrypted files

There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:

  • We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
  • Download Data Recovery Pro (commercial)
  • Install and scan for recently deleted files. Data Recovery Pro

Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
