Sglh ransomware (virus) - Decryption Methods Included

Sglh virus Removal Guide

What is Sglh ransomware?

Sglh ransomware is the threat that asks for the payment in exchange for the alleged decryption tool

Sglh ransomwareThis is a malicious program designed to lock all personal files and then demand ransom in exchange for a decryptor

Sglh ransomware is a cryptovirus that encrypts all non-system files on the victim's machine and then demands a ransom to unlock them. All personal files, such as documents, archives, databases, pics, and so on, are locked and appended with a .sglh extension. Like its whole family of Djvu ransomware, as soon as malware is done with encryption, a ransom note, titled _readme.txt, is created in all compromised folders. All encryption is done using a military-grade RSA[1] algorithm.

Within the ransom note, developers of the Sglh virus explain to the victims that all of their essential data is locked and only they have the power to unlock it, i.e., have the necessary decryption tool. The cybercriminals offer to send them one file via the or emails for free decryption, thus proving that they really do have the required decryption tool/key. Furthermore, a link is given to a video where the victims can witness the said tool in action. In a nutshell, the criminals are trying very hard to convince their victims that they will definitely send the required software after meeting their demands.

Virus removal Elimination of ransomware should be entrusted to professional anti-malware software
System tune-up System files and settings might have been changed for the virus to complete its mission, to undo all altercations use the powerful FortectIntego tool

The decryption tool's price and terms are the same as with its previous versions (Agho, Jdyi, Epor, etc.) – $490 if the victims contact the perpetrators within 72 hours of the infection. If not, the price is doubled to $980.

Although it is not mentioned in the ransom note, we can safely speculate that the preferred payment method will be in cryptocurrency Bitcoins. Sglh virus is identical to other threats in the same family. Two emails (, are provided to establish contact with the criminals by sending them the victim's unique appointed ID along with one encrypted file.

Meeting the demands of criminals isn't the best idea because victims could get scammed. Search for alternative methods to restore the encrypted data, for example – from your backups. It's a tough choice, but every owner of an infected device has to make it.

We, along with other experts,[2] advise deleting the malware from the device. The longer it stays in the computer system, the more damage it could do (for example, Djvu versions are known to inject data-stealing modules into Google Chrome or another web browser and harvest login credentials or other sensitive information), so use SpyHunter 5Combo Cleaner or Malwarebytes to remove Sglh ransomware automatically.

These apps might protect from such misfortunes in the future if kept up to date. Detection[3] names and the whole procedure of eliminating the virus can get affected by the threat itself when it manages to change particular settings or disable programs. So you may benefit from Safe Mode.

Sglh ransomware virusThe crypto-virus stems from one of the most prominent malware families around - Djvu

Sending your money shouldn't be an option

The payment that virus creators ask from victims can be convincing. Especially when some of these actors try to scare people into paying or promises discounts for the first 72 hours like this malware family. However, since this is a well-known family, you shouldn't think about transferring money because malicious actors do not care for your files and this is not the way to fight ransomware at all.

When Sglh ransomware removal is completed, you're not out of the woods yet. You have to check your system files and settings for any irregularities that might cause your device to exhibit abnormal behavior, such as crashing, severe lag, etc. The FortectIntego tool will locate and fix any damage the virus might have to the system settings/files.

Message from the developers of the ransomware to the victims (from _readme.txt file) reads:


Don't worry, you can return all your files!

The only method of recovering files is to purchase decrypt tool and unique key for you.

The option for decrypting .sglh files

It is a known fact within the tech-savvy community that Djvu family ransomware, along with the file virus, is spread out using illegal activation kits (popularly knows as cracks)[4] either for software or games. These infected toolkits are distributed via file-sharing platforms like the torrent site The Pirate Bay and others.

Immediately after a soon-to-be victim downloads a crack, for let's said, Adobe Photoshop Essentials, a payload file of Sglh ransomware executes itself, initiating the encryption. People should stay away from these sites and support their beloved software developers by purchasing their products directly from them or official distributors.

Sglh virus detection rateSglh virus can be stopped by many security programs before it manages to encrypt all files on the system

Now about the file recovery. If you had backups – no worries, just remove the virus, check system health with a proper tune-up tool, and retrieve .sglh files easily. If you didn't, please export all appended files to an offline storage device – such as a USB drive, and wait for the decryption tool to be created.

Researchers are working constantly for this cause, so be patient, and check back with us from time to time, as we update our readers with all the latest news. If you're very impatient, check out recovery options for experienced computer users at the bottom of this article, they might be helpful.

Bonus: Recover your data

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

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

Try to recover files using the Data Recovery Pro

  • 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 Sglh ransomware;
  • Restore them.

Try using another useful Windows OS tool – Windows Previous Version

Using this feature users might be able to retrieve file one by one.

  • 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”.

If Shadow Copies are intact Shadow Explorer will help

Possible decryption tool for the ransomware

There is a company called Emisoft that focuses on Djvu family ransomware decryption tools. Since this file virus is brand new, the decoder might not work, but there's always hope that the software company will soon add a decryption key for this virus too. Download the toolkit and try it out at your own risk.

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

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
