Ssoi is a harmful computer virus capable of changing the extensions of your most important files, thus making them inaccessible. A complex encryption process used by Ssoi is what allows this malicious program to block the access to the data of its victims.

The Ssoi virus file ransom note

Detecting your most valuable files and taking them hostage is the main job of Ssoi. This is a Ransomware threat, which is designed to secretly apply a special encryption to your documents, images, audios, videos, archives and certain system files, for the purpose of later asking you to pay a ransom for their decryption. Such type of action is a direct form of blackmailing, and the victims, which are attacked, are ruthlessly threatened to make a payment to the hackers if they ever want to access their files again. If you have become a victim of Ssoi or Rguy, you probably wonder if there are any alternatives for deal with this nasty infection and how could you possibly save your data without paying the hackers. Fortunately, we might be able to help you with some file-restoration tips as well as with the removal of Ssoi. On this page, our “How to remove” team has prepared a detailed Removal Guide, which can guide you through the detection and elimination process of the Ransomware. But in order to be able to detect it correctly, let us give you a general idea of what you are dealing with.

The Ssoi virus

The Ssoi virus is a new threatening program of the Ransomware type that employs military-grade encryption to seal the files of its victims. The encryption that the Ssoi virus uses can keep the attacked files unavailable even after the infection itself has been removed.

A perfect tool for online blackmailing, Ransomware has been gaining more and more popularity among the cyber-criminal circles in the recent years. The hackers who create such malicious pieces of software use them to target everyone on the Internet, with the idea of extorting money out of them through a simple yet highly effective scheme. They secretly infect the computer with a malicious file-encrypting virus and let it place its complex encryption on all the files, which can be found there. The infection may also change the file extensions and make the affected files impossible to open or read with any software unless a certain amount of money is paid as ransom for their decryption. Oftentimes the hackers threaten that the decryption key would get destroyed if the money isn’t paid within a specific period of time.

As a typical representative of the Ransomware cryptovirus class, Ssoi operates in pretty much the same way which is why it is regarded as a file-encrypting Ransomware. The presence of Ssoi on your machine can cause serious loss of data if you are not able to decrypt it, as well as some other harmful consequences for the entire system. This malware usually generates an automatic ransom-demanding message the moment it completes its secret encryption process and prompts the victims to immediately pay a certain amount of money if they want to obtain a decryption key. Ssoi threatens that the files will remain encrypted forever, in case the ransom payment is not released within a given deadline. This makes most users panic and give their money to the hackers without researching for other alternatives. Such behavior, however, is caused by fear and frustration and can hardly ever be a good solution to the Ransomware attack.

The Ssoi file decryption

The Ssoi file decryption is usually the only surefire way of getting any of the locked files back. The problem with the Ssoi file decryption is that it requires you to have a special decryption key that is in the hands of the hackers who you to pay for this key.

The .ssoi file virus

To our and your misfortune, if a threat like Ssoi attacks your system and encrypts the data, found inside, there are very few things, which could eventually save it and restore things back to normal. One is the application of a correct decryption key by using a specialized decryptor tool (more on that in the guid) and the other is the recovery of the files through external backups.

In case that you have your own file backups, your problem is more or less solved and the only thing you need to do before you copy them to the computer is to remove Ssoi from the system by either using the professional anti-malware tool from this page or by following the instructions from the Removal Guide below.

If you don’t have backups, however, you might be thinking of paying the ransom with the hope of obtaining the decryption key that the hackers offer. Now, we suggest you keep this idea as a very last option because it holds a great risk of losing your money without actually being able to recover anything. Just think about what would happen if the crooks don’t send you a decryption key despite you having paid them – there’s nothing that could be done in such a case to get the money back? Or what will happen if the key they give you doesn’t work? Again, your money would be gone and your data would still be inaccessible. That’s why, we suggest you try every other possible solution first and if nothing works, only then risk your money in this criminal scheme.

Below, in the file-restoration section, we will give you a few more possible solutions, which, despite the fact that they may not guarantee complete recovery, are still preferable in comparison to paying ransom to the criminals. To give them a try, you will first need to take care of your system and remove Ssoi. Otherwise, you will not be able to use your computer safely and whatever you eventually manage to recover may become encrypted again.

The fastest way to clean your PC completely is to run a scan with the professional malware-removal tool, available on this page. You can also use the instructions in the Removal Guide but be very careful in order to avoid deleting anything that’s actually important to your system. In case of confusion, you can always leave us a comment or contact a professional of your choice. Just don’t sponsor the hackers if there’s another possible way of overcoming this issue.

Using the Task Manager, you need to end all Ransomware processes and remove their associated folders. To do that, use the Ctrl + Shift + Esc keyboard shortcut and go to Processes. Look for processes with strange names or processes that consume an excessive amount of CPU and Memory when launched. If any of these entries look questionable, do a Google search to see if there are any complaints of them being a danger. Next, right-click and access the folders for those processes (Open File Location).

Use the free scanner we’ve provided below to scan all files in those directories. It is important that a process be terminated if one or more of the files in its folder are deemed to be harmful by a scanner.

    If the scanner detects malicious files in the processes, go to the Task Manager, right-click on the related process, then press End Process. After that, remove the files associated with that process from the system.

    Use the Start Key and R key combination to open a Run box on the screen. In it, copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    This will open the Hosts file in Notepad.  Look under Localhost to see whether there are any suspicious IPs mentioned below. If you find anything disturbing, copy them all and post them in the comments section. In the event that we detect a danger, we will tell you what to do.

    After that, enter msconfig in the Start Menu search field, press Enter to open the System Configuration window, and check out which startup items are enabled on your system. 

    Look through the startup entries and deactivate the ones you aren’t familiar with and/or those that appear to be untrustworthy, then click OK to finish the process.

    Open the regedit.exe app by typing its name into the Start Menu search field. To open the program, Windows will ask for your permission. Click Yes to continue.

    Afterwards, click Edit at the top of the Registry Editor window to begin searching for entries associated with the Ransomware, then click Find, type Ssoi in the search field that appears, and click Find Next again to continue searching. The detected item should be deleted. If the search returns other Ssoi-related items in the results, they should also be carefully removed. You may need to repeat the search until you have removed all traces of Ssoi from your system.

    In the Start Menu search field, type “Folder Explorer Options” then enter the Folder Options settings and select the View option. Make sure the Show hidden files, folders and drives option is enabled by checking the checkbox.

    Then, in the Start Menu search field, type each of the following locations below and press Enter. 

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    The files in the newly opened folders may then be sorted according to the date they were created. Remove anything that has been added around the time the Ransomware infection occurred. Also, select everything in the Temp folder and delete it to remove any temporary files from the system. Simply click Ctrl + A to select all files in Temp, then hit Del to remove them all to make this process faster.


    How to Decrypt Ssoi files

    Even for experts, dealing with the implications of ransomware data encryption may be difficult.  However, there are some file-restoration tools that may allow you to decode encrypted data. To have success with them, though, you first need to determine what variant of Ransomware you’re dealing with. Look at the end of the encrypted files and their file extensions to obtain this information.

    A new Djvu Ransomware

    STOP Djvu Ransomware is the latest Djvu ransomware variant that you may encounter. This particular threat distinguishes from others because of the .Ssoi file encryption that it add to the encrypted data.

    Fortunately, there is a file-decryption tool included in the link below that may help you retrieve data encoded by this particular ransomware variant. It may be downloaded by clicking on the link provided.


    Run the decryption tool that you’ve downloaded as an administrator, then select “Yes” to start it. Please read the included instructions and the related license agreement carefully before starting. The decryption process will begin when you press the Decrypt button.

    If you need to decode files encrypted using unknown offline keys or online encryption, proceed with caution, as this tool may not be able to decode them. If you have any questions or concerns, please feel free to post them in the comments area down below.

    Important! Before attempting to recover data that has been encrypted, make sure to thoroughly search your computer for ransomware-related files and harmful registry entries.  

    A Trojan or Rootkit may be preventing you from manually removing Ssoi from your computer, despite your best efforts to remove the Ransomware. If a computer is infected with Ransomware and other malware, it is typical for the two to work together. Anti-malware software that can remove all dangers is ideal in these situations because it prevents them from working together to help one another. We’ve included a link to one such effective removal program in this guide, and we highly recommend that you use it if you’re still having issues with Ssoi. If you have Ssoi-related malware on your computer, this page’s free online virus scanner and the recommended anti-virus software can help you remove it.
