What is Quax0r ransomware?

Quax0r ransomware is a malicious Windows program designed to encrypt your files

Quax0r ransomware

Quax0r is a ransomware-type virus that could break into your device via various methods – spam emails, malicious links, software cracks, and similar. Once on the system, Windows files are immediately altered, many new ones are dropped, and some are also deleted. This significantly alters how the OS operates, allowing the virus to start its main goal.

After the system is ready, the malware quickly scans the device for personal files, such as pictures, videos, documents, and databases, and encrypts them with a strong encryption algorithm.[1] Unlike other ransomware, Quax0r does not append any extensions to the affected data, although they can no longer be opened regardless.

Soon after the file locking process, users are presented with a Command Prompt window which serves as a ransom note. It claims that users were infected with ransomware and that they need to contact the attackers via Discord (Nominatus#9251). We recommend not communicating with cybercriminals and using alternative methods for data recovery instead.

Name Quax0r virus
Type Ransomware, file-locking malware

File extension No file extensions are appended, and the names remain the same
Contact To contact the attackers, users are asked to write on Discord to account Nominatus#9251
Ransom note Command Prompt window pop-ups
File Recovery The only secure way to restore files is by using data backups. If such is not available or were encrypted as well, options for recovery are very limited – we provide all possible solutions below
Malware removal Disconnect the computer from the network and internet and then perform a full system scan with SpyHunter 5Combo Cleaner security software
System fix Once installed on the system, malware might seriously damage some system files, resulting in crashes, errors, and other stability issues. You can employ ReimageIntego PC repair to fix any of such damage automatically by replacing system corruption

A different kind of a ransom note

Unlike other malware, ransomware does not hide its presence; in fact, the developers of ransomware want victims to be aware of what happened to their computers so that they could have a higher chance of successful payments. Therefore, more avid cybercriminals make sure that a ransom note reaches the affected users.

There are plenty of ways how the most important information about infection and data recovery could be delivered to users. Crooks mostly rely on simple text-based files which can be opened in any text editing app, including the built-in Notepad. In some cases, malware authors produce a pop-up window that shows up soon after the data encryption.

In the case of the Quax0r virus, the ransom note shows in a rather unusual way – in a Command Prompt window. The message is relatively short and provides only contact details and what kind of ransomware users are dealing with:

All files have been encrypted by NominatusCrypto ( Quax0r ) contact the creator of this virus on discord Nominatus#9251 for more information if you restart then your account will be useless! files cannot be decrypted without paying the ransom to the creator!! live or die? make your choice now!

As usual, we stand against contacting cybercriminals behind the malware. It would only encourage crooks to infect more users, and they might never deliver the promised decryption tool.

Removal process explained

Ransomware is sometimes very misunderstood by victims as, even if they have heard about it before, they do not know much about its operational principles and what it can actually do. It is important to perform Quax0r ransomware removal in the correct order, or it may continue to encrypt the incoming files.

You should star tart by disconnecting your PC from the internet. Upon installation, malware connects to a remote C&C server[2] to assign a unique ID to each of the victims. It can also be used for communication purposes, which would allow the attackers to send commands to be executed remotely. This connection should be severed before proceeding:

  • Type in Control Panel in Windows search and press Enter
  • Go to Network and InternetNetwork and internet
  • Click Network and Sharing CenterNetwork and internet 2
  • On the left, pick Change adapter settingsNetwork and internet 3
  • Right-click on your connection (for example, Ethernet), and select DisableNetwork and internet 4
  • Confirm with Yes.

As soon as the virus is no longer active via the internet, it should be removed with SpyHunter 5Combo Cleaner, Malwarebytes, or another powerful security software. It is important to update anti-malware definitions before proceeding. In case ransomware is tampering with the removal process, you can always access Safe Mode and attempt the elimination process from there:

Windows 7 / Vista / XP

  1. Click Start > Shutdown > Restart > OK.
  2. When your computer becomes active, start pressing the F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
  3. Select Safe Mode with Networking from the list.Windows XP/7

Windows 10 / Windows 8

  1. Right-click on the Start button and select Settings.
  2. Scroll down to pick Update & Security.
  3. On the left side of the window, pick Recovery.
  4. Now scroll down to find the Advanced Startup section.
  5. Click Restart now.Recovery
  6. Select Troubleshoot.Choose an option
  7. Go to Advanced options.Advanced options
  8. Select Startup Settings.Startup settings
  9. Click Restart.
  10. Press 5 or click 5) Enable Safe Mode with Networking.Press F5 to enable Safe Mode with Networking

Remember, security software is not only useful when trying to remove infections from the system, but it also serves as your first line of defense against cyberattacks. That's why it is important that it runs in the background at all times, and its warnings should never be misinterpreted as false positives.[3]

Data recovery

Many users mistakenly believe that ransomware-encrypted files can be restored as soon as the scan with anti-malware software is performed. However, this is not the case as file encryption and system infection are two separate processes, even though the former wouldn't be possible without the latter.

There are also people on the other side of the spectrum who assume that their files are permanently destroyed. While this can happen in certain circumstances, it is usually not the case. We always recommend our users to imagine that their files have been locked by a unique password, and only the cybercriminals have access to it.

Nonetheless, not everything is lost as, we already explained, contacting crooks is not the best solution out there. Instead, we recommend trying alternative methods, such as waiting for the decrytpion tool or attempting to restore Quax0r files with the help of recovery software.

Note that it is very important you backup all the encrypted files before you proceed, as recovery software might permanently damage them, and even a working decryptor would not be able to restore them.

  • Download Data Recovery Pro.
  • Double-click the installer to launch it.

  • Follow on-screen instructions to install the software.Install program
  • As soon as you press Finish, you can use the app.
  • Select Everything or pick individual folders where you want the files to be recovered from.
  • Press Next.
  • At the bottom, enable Deep scan and pick which Disks you want to be scanned.Select Deep scan
  • Press Scan and wait till it is complete.
  • You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
  • Press Recover to retrieve your files.Recover files

System fix

After malware infection, Windows is no longer the same, as some system files might get damaged or even destroyed. This can result in system instability – crashes, failure to launch programs, BSODs, etc. If you suffer from these problems after eliminating the infection, use data recovery software as explained below.

  • Download ReimageIntego
  • 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 immediatelyReimage scan
  • 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

By employing this tool, 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 if things go very wrong for one reason or another.

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.
