Quantum Locker ransomware is the cryptovirus that encrypts files and marks them using the particular appendix

Quantum Locker ransomware

Quantum Locker ransomware modifies files and locks them to have a reason for the direct extortion message. The particular cryptovirus marks data using .quantum appendix. Once these files are encoded, the user cannot open the image, audio, video file, or document. This infection is releasing a file with the message from criminals demanding payment in cryptocurrency. This is the preferred method due to the tracing issues because cybercriminals want to remain anonymous and make a fortune.

README_TO_DECRYPT.html file appears in various places on the machine, so users see and follow the instructions. However, the payment is never a recommended solution for any ransomware. Attackers can cause major issues on the machine without the file-locking, so make sure to remove the Quantum ransomware virus instead. And we list all alternate options and steps below.

Name Quantum ransomware
Type Cryptovirus, file-locker
File marker .quantum
Ransom note README_TO_DECRYPT.html
Issues The virus demands money after locking the commonly used files, it affects performance and causes damage to functions and features of the computer
Distribution Files with malicious purposes get attached to emails, included in pirating packages. Malicious macros[1] help the attacker to spread the infection
Contact information Tor website chat
Removal Anti-malware tools can detect the threat[2] on the machine and remove the particular files 
Repair Malicious virus damage can be causing all the performance problems, so you need to solve that with FortectIntego

 Virus removal

Quantum ransomware is a particular infection used to encrypt files and demand payment in exchange for the alleged decryption tool. It is rarely possible for free because threats use powerful methods and makes major changes. You need to remove the virus as soon as the data got locked.

Anti-malware tools like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes are the ones that can help with the virus termination. The elimination is successful if you use proper antivirus applications. The Quantum ransomware removal process can be quick if you run the proper scan on the machine. The system check indicates all possibly dangerous or malicious pieces for you.

Free data recovery tools are not easy to develop, and file recovery is in general a difficult process. If you have no backups, these files restore options become more limited. Quantum Locker ransomware virus is a new threat and has not resembled other families, so remove it and make sure to clear the machine fully right away.

Repair issues with the machine

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. 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
    Reimage download
  • If User Account Control (UAC) shows up, select Yes
  • Press Install and wait till the program finishes the installation processReimage installation
  • 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.Reimage results

Issues with the ransomware and crypto attackers

Quantum Locker ransomware gives victims a certain time period to react and contact attackers, so those files that got locked do not get published online. The infection is claiming that there are no options, so people fall for the scary claims and believe every word listed in the ransom note.

The demanding message reads:

Your ID:      

This message contains an information how to fix the troubles you've got with your network.

Files on the workstations in your network were encrypted and any your attempt to change, decrypt or rename them could destroy the content.
The only way to get files back is a decryption with Key, provided by the Quantum Locker.

During the period your network was under our control, we downloaded a huge volume of information.
Now it is stored on our servers with high-secure access. This information contains a lot of sensitive, private and personal data.
Publishing of such data will cause serious consequences and even business disruption.

It's not a threat, on the contrary – it's a manual how to get a way out.
Quantum team doesn't aim to damage your company, our goals are only financial.

After a payment you'll get network decryption, full destruction of downloaded data, information about your network vulnerabilities and penetration points.
If you decide not to negotiate, in 48 hours the fact of the attack and all your information will be posted on our site and will be promoted among dozens of cyber forums, news agencies, websites etc.

To contact our support and start the negotiations, please visit our support chat.
It is simple, secure and you can set a password to avoid intervention of unauthorised persons.

Password field should be blank for the first login.
Note that this server is available via Tor browser only.

Quantum ransomware creators can damage the particular processes and files on the machine, so the infection is affecting more than those files that are locked. The ransomware victim worries about files and wants to get those pieces recovered. It is not quick or easy.

Paying the ransom, however, does not guarantee that files will get decrypted. Criminals do not care about your belongings and the infected device needs a lot more work before you can use it again. The active virus can cause permanent damage if the Quantum ransomware removal is not started right away.

Try to find a decryptor for Quantum Locker ransomware

File encryption is a process that is similar to applying a password to a particular file or folder. However, from a technical point of view, encryption is fundamentally different due to its complexity. By using encryption, threat actors use a unique set of alphanumeric characters as a password that can not easily be deciphered if the process is performed correctly.

There are several algorithms that can be used to lock data (whether for good or bad reasons); for example, AES uses the symmetric method of encryption, meaning that the key used to lock and unlock files is the same. Unfortunately, it is only accessible to the attackers who hold it on a remote server – they ask for a payment in exchange for it. This simple principle is what allows ransomware authors to prosper in this illegal business.

Regardless of which crypto-malware affects your files, you should try to find the relevant decryptor if such exists. Security researchers are in a constant battle against cybercriminals. In some cases, they manage to create a working decryption tool that would allow victims to recover files for free.

Once you have identified which ransomware you are affected by, you should check the following links for a decryptor:

No More Ransom Project

If you can't find a decryptor that works for you, you should try the alternative methods we list below. Additionally, it is worth mentioning that it sometimes takes years for a working decryption tool to be developed, so there are always hopes for the future.

Quantum Locker ransomware is the virus that informs victims about the procedure via the ransom note. These claims listed by the cryptocurrency extortionists can be false and suggest scary outcomes, so people pay up and fall for the scamming techniques. Experts[3] offer to ignore these messages and avoid interaction with criminals.

The infection is serious and needs to be taken seriously. The threat removal process is crucial here, so make sure to run SpyHunterCombo Cleaner or MalwarebytesMalwarebytes and stop the active virus. Then you can focus on the Quantum ransomware virus damage and file repair that affects the further actions. As for the virus damage and leftovers, use FortectIntego.
