How to remove Nqhd ransomware

Nqhd ransomware is an infection that focuses on encryption because it provides the reason for direct money demands

Nqhd file virus is a malicious program designed to encrypt all personal data on the computer and then demand ransom for its return. Once inside the system, it encrypts all personal pictures, videos, documents, archives, and other files by using a strong encryption algorithm.^[1] The file-locking process ends in useless files. The virus also appends a .nqhd extension in the process to mark files affected by the ransomware. Victims can no longer access these files and are required to have a unique key that is in possession of cybercriminals behind the ransomware.

Once the encryption is complete, the 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.

People get encouraged to pay the demanded sum to virus creators, but even contacting them can go badly for victims. Nqhd ransomware is a cryptovirus that belongs to a malware family known as Djvu ransomware. This malware encrypts all the important files and restricts access to them. On the ransom note, cybercriminals explain that the only way to recover data is by paying ransom in Bitcoin.

These claims should encourage people to send money for the alleged recovery, but experts^[2] recommend staying away from these shady threat actors. There might be decryption options available for some of the versions, but generally, this family releases new versions every week, so researchers cannot provide the universal tool that successfully recovers all affected files for victims.

While it is true that Nqhd virus files require a unique decryption key to unlock them, 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. Remove the threat first and then worry about the issues with locked data.

Nqhd ransomware virus decryption option

According to the virus authors, victims need to contact them via email and provide their personal ID. Those IDs get formed during the encryption process. These keys are needed for the identification and decryption process later on. However, there are two particular ways these keys get formed. 

The ransomware is trying to connect with various remote servers, but cryptovirus might fail to do so. If it cannot properly communicate while encrypting your files, then the program uses a built-in encryption key that is not unique for every device. It is the same for each version of the virus. It means that all victims get the same ID.

This means decryption will be easier if offline keys are used instead of online ID numbers. However, that is rare with new versions like the Nqhd virus. The previous versions since August 2019 cannot be decrypted. Miia, Loov, Dehd are the ones that got released before this one and those are not using online IDs.

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.

More on file recovery options and virus removal

Nqhd virus is a serious threat, but do not forget that machine is affected more than file-locking. Your files are not the thing cybercriminals worry about. Money is their purpose and goal, so do not contact them and do not consider paying. You need to remove the ransomware as soon as possible.

That is achievable with particular anti-malware tools that are capable of detecting and removing threats with all related files. Antivirus programs like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes can locate possibly malicious files and treat them properly. The system can get cleaned. and your machine becomes virus-free. However, not that decryption is not the same as removing the virus.

Nqhd file virus can be eliminated, and those malicious processes terminated, but do not forget about performance improvement. You need to clear the infection, repair system functions, and then you can rely on particular file recovery options that are available to you.

Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.

While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.

Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important while dealing with this situation:

• Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
• Only attempt to recover your files using this method after you perform a scan with anti-malware software.

Install data recovery software

1. Download Data Recovery Pro.
2. Double-click the installer to launch it.
   
3. Follow on-screen instructions to install the software.
4. As soon as you press Finish, you can use the app.
5. Select Everything or pick individual folders where you want the files to be recovered from.
6. Press Next.
7. At the bottom, enable Deep scan and pick which Disks you want to be scanned.
8. Press Scan and wait till it is complete.
9. You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
10. Press Recover to retrieve your files.

Additional tips for dealing with ransomware

Nqhd ransomware is a serious infection that uses blackmail to get money from people, but there are additional issues with the infection. Malware alters various settings, files, adds other threats and files on the machine to ensure persistence. It might be even distributed with the help of trojans. All these infections come with their processes and damage.

There are things you can do to avoid the infection. The infiltration involves malicious files spread around with the help of spam emails or pirating services. If you avoid these platforms and stay away from opening random emails, you can avoid the infection in the first place.

The more common ways used to spread Nqhd ransomware like this include malicious files added to spam emails. Those emails can claim about order information, list links to shady sites. Also, these campaigns can use names like DHL, UPS, eBay other known companies and brands to attract the attention of the receiver.

Then the macro virus can be triggered with one click of a button that enables them on a Word or Excel file. Immediately after that, ransomware is executed. The particular family is known for spreading via cracks for games or software like Adobe, Photoshop. Unfortunately, that is not a process you could notice yourself, so file encryption is the procedure that indicates malware infection. Make sure to remove the virus.

Do not forget about the virus damage that can ensure persistence and lead to another round of Nqhd virus encryption. 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. You need to take care of that.

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 reinstallation 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.
