How to remove Shgv ransomware

Shgv ransomware is a data-locking computer infection built for cryptocurrency extortion

Shgv file virus is a malicious program designed to encrypt all personal data on the computer and then demand ransom for its return. The threat manages to infect the computer using the infected files. Once inside the system, it encrypts all personal pictures, videos, documents, archives, and other files by using a strong encryption algorithm, which also appends a .shgv extension in the process. Victims can no longer access these files and require a unique key that should help with decryption. The particular key costs $980 in Bitcoin.

Once the encryption is complete, Shgv virus drops a ransom note _readme.txt – instructions from cybercriminals. It explains to victims what happened to their files and claims that the only method to return them is by paying a ransom for a decryption tool. For negotiation purposes, crooks also provide emails manager@mailtemp.ch, helprestoremanager@airmail.cc.

The cryptovirus belongs to a malware family known as Djvu ransomware that has been active since 2018. Developers do release new versions weekly to this day. In the ransom note, cybercriminals behind the attack explain that the only way to recover data is by paying ransom in Bitcoin.

While it is true that Shgv virus files require a unique decryption key to unlock them, experts recommend not paying the ransom, as cybercriminals might not keep their promises, resulting in financial losses. In this article, we will explain how to get rid of malware and use alternative methods for data recovery.

Shgv ransomware is a virus that attacks Windows computers by using various infiltration methods. The most common for this family is related to pirating platforms and files with malicious code. The payload of this ransomware can get dropped when the spam email attachment is opened and downloaded on the machine. It is always advised by experts and researchers^[1] who advise staying away from such platforms.

According to the virus authors, victims need to contact them and provide their personal ID to get help. Once that is done, users should receive further instructions to proceed with the payment, provided in bitcoin cryptocurrency. Nonetheless, we do not recommend contacting the attackers because they might not deliver the required decryption tool. Check out the alternative methods we provide below instead.

Step 1. Try decryption options

Shgv is a type of virus that is classified as ransomware because it uses various processes just to have the purpose for a ransom demand. These threats are known for accessing user machines without permission and encrypting all files on them. This way, cybercriminals behind the attack can ask for a ransom payment in return for a unique key. The main cryptocurrency criminals want to get is Bitcoin.

The malware encrypts all files with the help of a powerful encryption algorithm and appends the unique extension to each of them. This is how names can be determined for these versions on the list. For example, .yjqs, .mljx, .yqal, .hgsh. Once encryption is finished, the attackers write their message and claim that they are willing to provide the decryption tool for a particular sum of money, to be paid in bitcoin cryptocurrency.

Another option for the decryption would be an official tool capable of unlocking those files. Unfortunately, a few years back, the family was decryptable, but those tools are no longer in use because processes got improved. These newest variants are rarely decryptable. it depends on online and offline IDs that either allow the decryption to happen with one general key or keep all victims from having their files restored. You can still try to decrypt those .shgv files.

If your computer got infected with one of the Djvu variants, you should try using Emsisoft decryptor for Djvu/STOP. It is important to mention that this tool will not work for everyone – it only works if data was locked with an offline ID due to malware failing to communicate with its remote servers.

Even if your case meets this condition, somebody from the victims has to pay criminals, retrieve an offline key, and then share it with security researchers at Emsisoft. As a result, you might not be able to restore the encrypted files immediately. Thus, if the decryptor says your data was locked with an offline ID but cannot be recovered currently, you should try later. You also need to upload a set of files – one encrypted and a healthy one to the company's servers before you proceed.

• Download the app from the official Emsisoft website.
• After pressing Download button, a small pop-up at the bottom, titled decrypt_STOPDjvu.exe should show up – click it.
• If User Account Control (UAC) message shows up, press Yes.
• Agree to License Terms by pressing Yes.
  
  
• After Disclaimer shows up, press OK.
• The tool should automatically populate the affected folders, although you can also do it by pressing Add folder at the bottom.
  
• Press Decrypt.
  
  

From here, there are three available outcomes:

1. “Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
2. “Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
3. “This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.

Step 2. Remove the infection properly

Shgv ransomware – a computer infection that encrypts all personal files with an army-grade encryption algorithm. However, there are many other issues that cryptovirus creates. Although decryption and file recovery can be possible, that is not the same as removing the infection.

The removal is best when performed using proper detection-based tools like anti-malware.^[3] Antivirus programs like SpyHunterCombo Cleaner can properly scan the machine and find all possible malware files. Malicious pieces related to the Shgv file virus can be detected and removed with tools like this, but MalwarebytesMalwarebytes or any other AV programs cannot repair those system files or decrypt locked data. Do not mix these things up.

Nevertheless, you need to remove the infection before doing anything else. A secondary round of encryption is possible when the virus is still active and without anti-malware tools, the threat cannot be terminated and stopped. You risk getting data permanently damaged if you allow the threat to run and still repair files using copies. Do not let Shgv file virus damage the machine further. 

Once a computer is infected with malware, its system is changed to operate differently. For example, an infection can alter the Windows registry database, damage vital bootup, and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not capable of doing anything about it, leaving it just the way it is. Consequently, users might experience performance, stability, and usability issues, to the point where a full Windows reinstall is required.

Therefore, we highly recommend using a one-of-a-kind, patented technology of FortectIntego repair. Not only can it fix virus damage after the infection, but it is also capable of removing malware that has already broken into the system thanks to several engines used by the program. Besides, the application is also capable of fixing various Windows-related issues that are not caused by malware infections, for example, Blue Screen errors, freezes, registry errors, damaged DLLs, etc.

• Download the application by clicking on the link above
• Click on the ReimageRepair.exe
  
  
• If User Account Control (UAC) shows up, select Yes
• Press Install and wait till the program finishes the installation process
• The analysis of your machine will begin immediately
• Once complete, check the results – they will be listed in the Summary
• You can now click on each of the issues and fix them manually
• If you see many problems that you find difficult to fix, we recommend you purchase the license and fix them automatically.

Step 3. Double-check for any remaining issues

Ransomware is a scary thing to think about, but there are ways you can protect yourself. When your computer gets infected with ransomware, the criminals will often plant additional malware. This means that Shgv ransomware virus can have other threats keeping the persistence of this cryptovirus and you need to get the infection properly removed.

Unfortunately, it may be difficult to remove the ransomware. This could be because the virus altered your settings or programs in some way so that you cannot use security features related to anti-malware tools such as firewall protection anymore. You can use SpyHunterCombo Cleaner or MalwarebytesMalwarebytes for the proper Shgv virus removal and double-check for affected pieces to ensure the machine is virus-free.

By employing FortectIntego also, you would not have to worry about future computer issues, as most of them could be fixed quickly by performing a full system scan at any time. Most importantly, you could avoid the tedious process of Windows reinstallation in case things go very wrong due to one reason or another.
