Adhubllka ransomware removal instructions
What is Adhubllka?
Adhubllka is the tile of a malicious program, classified as ransomware. Systems infected with this malware have their data encrypted and receive ransom demands for appropriate decryption tools/software. Its discovery is credited to S!Ri. As Adhubllka encrypts, it renames files by adding the ".ADHUBLLKA" extension. For example, a file originally titled something like "1.jpg" would appear as "1.jpg.ADHUBLLKA" - following encryption, and so on for all of the affected files. After this process is complete, a text file "read_me.txt" containing the ransom note - is created on the desktop.
The text file informs victims that their data has been encrypted and reassures them that it can be recovered. The compromised files (e.g. documents, photos, databases, etc.) have been encrypted with strongest encryption and unique key. The message states that the only way to restore them - is to purchase decryption tools/software and key (individually generated for each victim) from the cyber criminals behind Adhubllka ransomware. The price of these tools is left unmentioned, however supposedly a 50 percent discount is available, should users establish contact with the malware's developers within the first 72 hours. To receive further instructions, victims must write to the criminals via the email address provided. The note also alerts users that attempting to decrypt their files with third party software will render them undecryptable, i.e. damage them beyond repair. It is true that in most cases of ransomware attacks, decryption is impossible without the interference of individuals responsible. It might be possible, if the malicious program is still in development and/or has major bugs (flaws). Regardless, it is strongly advised against communicating with and/or meeting the demands of cyber criminals. They are not to be trusted, as there are no guarantees that they will hold their end of the bargain. Often, despite paying - users do not receive the promised decryption tools/software. Therefore, not only does their data remain encrypted and worthless, but they experience significant financial losses as well. Eliminating Adhubllka from the operating system will prevent it from further encryptions. Unfortunately, removal will not restore already affected files. The sole solution is recovering them form a backup, if one was made prior to the attack and was stored in a different location.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Ransomware is designed to encrypt data and demand payment for its decryption. Sivo, Horsedeal, Oled, Adair are a couple examples of malicious software belonging to this class. There are two main differences between them - the cryptographic algorithm they use (symmetric or asymmetric) and the ransom size. The demanded payments usually vary between three-digit and four-digit sums (in USD). Cyber criminals tend to prefer digital currencies (mostly cryptocurrencies), due to transactions of them being difficult/impossible to trace. To ensure data integrity, it is recommended to keep backups in unplugged storage devices and/or remote servers. It is best to store multiple backups in several separate locations.

How to protect yourself from ransomware infections?
Dubious and/or irrelevant emails should not be opened. Any attachments (or links) found in suspicious mail - must never be opened, as they are a potential source of an infection. All downloads should be done through official and verified channels. The same extends to software activation and updating, which should only be done with tools/functions provided by legitimate developers. Illegal activation tools ("cracks") and third party updaters are advised against use, due to high risk of malware installation. It is paramount to device/user safety to have a dependable anti-virus/anti-spyware suite installed. These programs are to be kept up-to-date, used to perform regular system scans and removal of detected threats/issues. If your computer is already infected with Adhubllka, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Adhubllka ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Adhubllka ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Adhubllka are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Adhubllka ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
