Hets ransomware removal instructions
What is Hets?
Hets is a the name of a piece of malicious software, belonging to the Stop/Djvu ransomware family. Devices infected with this malware have their data encrypted and cyber criminals behind this infection - demand a ransom to be paid for decryption. As it encrypts files, it retitles them with the ".hets" extension. For example, a filename like "1.jpg" would appear as "1.jpg.hets", and so on for all of the compromised files. Once this process is complete, a text file named "_readme.txt" is created on the desktop.
The text file informs victims that their data has been encrypted and they need a specific decryption tool and unique key to decrypt it. These necessary tools are to be purchased from developers of Hets. The ransom is stated to be $980, however it can be halved by 50%, if users contact the cyber criminals within 72 hours. As proof that the files can be recovered, free decryption of one file is offered. The test file will be decrypted, if it does not contain valuable information (likely meaning that it cannot be a database, backup, large excel sheet and the like). There are email addresses provided, through which victims are to contact the criminals and send them a file to test decryption. It is also added that if there is no response from the developers within 6 hours, users are to check their "Spam/Junk" folders for the reply. After the payment is made, users are promised decryption tools/keys, which will allow them to recover their data. In most cases of ransomware infections, without the involvement of the individuals responsible - manual decryption is impossible. It may be viable, if the malicious programs is still in development and/or has key flaws/bugs. Regardless, it is expressly advised against communicating with and/or meeting the demands of cyber criminals. Often, despite paying - victims do not receive the necessary tools and their files remain encrypted. Therefore, aside from permanent data loss - users experience financial losses as well. Hets must be removed to prevent it from further encryptions, however removal will not restored already affected data. The only possible solution is recovering it from a backup, if one was made prior to the infection and was stored in a different location.

Msop, Rote, Zobm, Righ are a few examples of other malicious software, belonging to the Djvu ransomware family. Other ransomware (unassociated in the aforementioned fashion), include BigBossRoss, ROGER, Calum, etc. All malware under this classification is designed to encrypt data and demand payment for decryption tools/software. Crucial differences are the cryptographic algorithm (symmetric or asymmetric) used for the encryption and ransom size. These payments typically vary between three and four digit sums, with digital currencies being preferable. The latter is due to transactions of such being difficult/impossible to trace. To ensure data safety, it is recommended to keep backups in remote servers and/or in unplugged storage devices. Ideally, several backups should be stored in separate locations.

How to protect yourself from ransomware infections?
Unknown, suspicious and irrelevant emails should not be opened. The same extends to files and links found in such suspect mail. These files must never be opened as they are the source of a potential infection. It is recommended to only use official and verified download channels. Software should be activated and updated using tools/functions provided by legitimate developers, not with illegal activation ("cracking") tools and third party updaters. Users are urged to have a dependable anti-virus/anti-spyware suite installed and kept updated. It should be used for regular system scans and removal of detected threats. If your computer is already infected with Hets, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

IMPORTANT NOTE! - As well as encrypting data, ransomware-type infections from the Djvu malware family also 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 done to prevent users from accessing malware security websites and seeking 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).
Screenshot of websites added to Windows hosts file:
There are currently two versions of Djvu ransomware infections: old and new. The old versions were designed to encrypt data by using a hard-coded "offline key" whenever the infected machine had no internet connection or the server was timing out/not responding. Therefore, some victims were able to decrypt data using a tool developed by cyber security researcher, Michael Gillespie, however, since the encryption mechanism has been slightly changed (hence the new version, released in August, 2019), the decrypter no longer works and it is not supported anymore. If your data has been encrypted by an older version, you might be able to restore it with the another tool developed by Emsisoft and Michael Gillespie. It supports a total of 148 Djvu's variants and you can find more information, as well as download link and decryption instructions in Emsisoft's official page.

Additionally, Emsisoft is now providing a service that allows to decrypt data (again, only if it was encrypted by Djvu variants released before August, 2019) for those victims who have a pair of the same file before and after the encryption. All victims have to do is upload a pair of original and encrypted file to Emsisoft's Djvu decryption page and download the aforementioned decryption tool (the download link will be provided after uploading files). Note that the file processing may take some time so be patient. It is also worth mentioning that the system must have an Internet connection during the entire decryption process, otherwise it will fail.
