Superuser ransomware removal instructions
What is Superuser?
Superuser is a ransomware-type virus discovered by malware security researcher, Michael Gillespie. Immediately after infiltration, Superuser encrypts most files and appends filenames with the "+firstname.lastname@example.org" (e.g., "sample.jpg" is renamed to "email@example.com"). Once encrypted, data immediately becomes unusable. Following successful encryption, Superuser generates a text file (named "INSTRUCTIONX.txt") and places a copy in every existing folder.
Research shows that many victims of this virus are located in Belarus. Therefore, there is a high probability that developers live in this country. As usual, the new text file contains a message stating that to decrypt data, victims must contact Superuser's developers via an email address provided. No additional information is provided. Therefore, it is currently unknown whether Superuser uses symmetric or asymmetric cryptography, however, decryption will certainly require a unique key generated individually for each victim. Furthermore, all keys are hidden on a remote server controlled by cyber criminals (Superuser's developers). After contacting these people, users are asked to pay ransoms for their keys. The cost is also unconfirmed - these details are provided via email, however, cyber criminals typically demand $500-1500 in Bitcoins, Monero, or another cryptocurrency. Regardless of the cost, do not pay. Most cyber criminals ignore victims once payments are submitted. Paying typically gives no positive result and users are simply scammed. You are strongly advised to ignore all requests to contact these people or pay any ransoms. Unfortunately, there are no tools capable of cracking Superuser encryption and restoring data free of charge. There is only one solution: to restore everything from a backup.

Superuser shares many similarities with Evil Locker, RPD, KyMERA, and dozens of other ransomware-type viruses. Note that, although these viruses are developed by different cyber criminals, their behavior is identical - all encrypt data and make ransom demands. They typically have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Most use cryptographies (e.g., RSA, AES, and similar) that generate unique decryption keys. Therefore, unless the virus is still in development or has certain bugs/flaws, returning browsers to their previous states is impossible. Ransomware presents a strong case for maintaining regular data backups, however, store them on a remote server or unplugged storage device. This will prevent ransomware from encrypting backups together with regular files.
How did ransomware infect my computer?
How to protect yourself from ransomware infections?
The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing/updating software. Think twice before opening email attachments. Files that seem irrelevant or have been sent by a suspicious/unrecognizable email addresses should never be opened. In addition, download your programs from official sources only, using direct download links. Third party downloaders/installers are used to distribute rogue apps, and thus these tools should not be used. The same rule applies to software updates. It is very important to keep installed programs up-to-date. To achieve this, however, use implemented functions or tools provided by the official developers only. We also strongly recommend that you have a legitimate anti-virus/anti-spyware suite installed and running. If your computer is already infected with Superuser, we recommend running a scan with Reimage Repair Tool for Windows to automatically eliminate this ransomware.

- What is Superuser?
- STEP 1. Superuser virus removal using safe mode with networking.
- STEP 2. Superuser ransomware removal using System Restore.
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup. Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings". Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

Windows 10 users: Click the Windows logo and select the Power icon. In the opened menu click "Restart" while holding "Shift" button on your keyboard. In the "choose an option" window click on the "Troubleshoot", next select "Advanced options". In the advanced options menu select "Startup Settings" and click on the "Restart" button. In the following window you should click the "F5" button on your keyboard. This will restart your operating system in safe mode with networking.

Log in to the account infected with the Superuser virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Superuser ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Superuser ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Superuser are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Superuser ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
