Myskle ransomware removal instructions
What is Myskle?
Myskle is one of the many ransomware-type programs that are designed to prevent victims from accessing their files unless they pay a ransom for cyber criminals who designed it. This program belongs to Djvu ransomware family, the person who discovered it is Michael Gillespie. Myskle is designed to change every encrypted file's name by adding the ".myskle" extension to it. For example, it renames a file named "1.jpg" to "1.jpg.myskle" and so on. It also puts a ransom note (the "_readme.txt" file) in all folders that contain any of the encrypted files.
As stated in the ransom note, victims cannot access their files without decrypting them with a tool and key that cost $980. However, they can be purchased for less ($490) if Myskle's developers will be contacted in 72 hours after encryption. It is mentioned that the only way to decrypt encrypted files is to use the tool that only these cyber criminals have. Unfortunately, it is true. To prove that they have it, they offer a free decryption of one file that can be sent to them via firstname.lastname@example.org or email@example.com email address, or via Telegram account @datarestore. Thee is an offline decryption tool that could be capable of decrypting files encrypted by Myskle, however, only if the server that is used by cyber criminals was not responding or there was no Internet connection during the encryption process. Another way to restore files without having to contact or pay these cyber criminals is to use data backup for that. We do not recommend to contact any ransomware developers. Typically, they do not send their victims the decryption tools/keys, even if all their demands are met (ransom is paid).
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
As a rule, ransomware-type programs have two main things in common: they encrypt data and keep it encrypted unless a ransom is paid/decryption tool is purchased. The main differences between them usually are the price of a decryption tool and cryptography algorithm (symmetric or asymmetric) that is used to cause the encryption. Unfortunately, people who have their computers infected with ransomware do not have many choices. They are forced to contact cyber criminals or to restore files from data backup. That is why it is important to have one created and to keep it on a remote server (like Cloud) or unplugged storage device. A few examples of other programs that are similar to Myskle are Muslat, Kjh and Zoh.
How did ransomware infect my computer?

To eliminate Myskle virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Web links and attachments that are presented in irrelevant emails received from unknown, suspicious addresses should not be opened (or clicked). The safest option is to ignore emails of this type (not to open their contents). Another important thing is to download all software from official and trustworthy websites and using direct download links. We do not recommend to use third party downloaders, unofficial/unreliable websites and other sources of this kind for that. Furthermore, all installed programs should be updated with tools (or functions) that are designed by official developers. If some installed program is not free, it should be activated/registered properly. It is not legal to use software 'cracking' tools and they often infect computers with malware. One more important thing is to have a reputable anti-virus or anti-spyware suite installed and to keep it enabled at all times. Additionally, we recommend to scan the operating system for viruses regularly. If your computer is already infected with Myskle, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Screenshot of files encrypted by Myskle (".myskle" extension):
Malware researcher Michael Gillespie has developed a decryption tool that might restore your data if it was encrypted using an "offline key". As we've already mentioned, each victim gets a unique decryption key and all of them are stored in remote servers controlled by cyber criminals. These are categorized as "online keys". However, there are cases when the infected machine has no Internet connection or the server is timing out/not responding. If that is the case, Myskle will use an "offline encryption key", which is hard-coded. Now it is worth mentioning that cyber criminals change offline keys every now and again. This is being done to prevent multiple encryptions with the same key. Meanwhile, Michael Gillespie continually gathers offline keys and updates the decrypter. However, the chances of successful decryption are still very low, since only a very small portion of "offline keys" has been gathered. You can download the decrypter by clicking this link (note that the download link remains the same, despite the fact that decrypter is being continually updated). Your files will be restored only if the list of gathered keys will include the one that was used to encrypt your data.

As with most of ransomware from Djvu family, Myskle also displays a fake Windows update pop-up during the encryption:
IMPORTANT NOTE! - Aside from encrypting data, ransomware-type infections from Djvu malware family also installs a trojan-type virus called AZORult, which is designed to steal various account credentials. Moreover, this malware family is designed to add a number of entries to the Windows hosts file. The entries contain URLs of various websites, most of which are related to malware removal. This is carried out with the intention of making users unable to access malware security websites and seek help. Our website (PCrisk.com) is also on the list. Removing these entries, however, is simple - you can find detailed instructions in this article (note that, although the steps are shown in the Windows 10 environment, the process is virtually identical on all versions of the Microsoft Windows operating system).

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 Myskle 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 Myskle ransomware.
Note that Windows 10 Fall Creators Update includes "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default this feature automatically protects files stored in Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
