Ooii Virus

Ooii

Ooii is a ransomware infection that enters your PC without your consent, searches for the most used files and encrypts them with complex code. After doing this, Ooii displays a screen message in which the hackers demand that you pay a ransom for the decryption of the encrypted files.

Ransomware viruses like this one are known to be the most dangerous cyber threats of all known kinds of malware. They are also some of the hardest to remove. All such viruses are used by hackers to make some money out of your misery. Ooii is especially bad because it targets your most commonly used files and prevents you from accessing them for an indefinite period of time or until you agree to pay the required ransom.

The Ooii virus

The Ooii virus is a Ransomware-based infection that is normally used in an extortion scheme. The Ooii virus uses secret file encryption to restrict access to certain digital files and then blackmails its victims to pay ransom for them.

Threats of this kind are typically distributed with a close friend – a Trojan horse virus. This is how these two help each other to carry out their mostly unlawful and harmful tasks. The infection process actually starts with a vulnerability. It could either be an outdated program or it could be an existing system security weakness such as the absence of an updated and reliable security tool. The Trojan detects and exploits such vulnerabilities to let the Ransomware inside your computer without being detected. Once there, the Ransomware carefully searches all of the folders on your PC for files. The malware determines the importance of the files by detecting how frequently they are opened or used. Then it encodes them one by one and changes their file extension with an unfamiliar extension that no program can recognize.

The .Ooii file recovery

The .Ooii file recovery is a process that, in most cases, requires professional assistance. The .Ooii file recovery is also possible if you have personal data backup sources or you obtain a working file decryption key from the hackers.

In most cases, after the Ooii ransom message has notified you about the attack and you confirm that your files have indeed been encrypted, you are left with the option to pay the required ransom in order to obtain a special decryption key from the hackers who are behind the ransomware.

However, it really is a gamble to give criminals money and expect them to recover your encrypted files. They may vanish once they receive the payment and, in this case, you will lose not only the chance to recover your files but also your hard-earned money. At the same time, if you refuse to pay the ransom, you can try to find another solution, such as software or an expert that can help you solve the problem with Ooii. Irrespective of what your decision is, make sure you calculate your risks, read more about alternative options, ask for help from an expert, become a forum member, or actively seek online for new decryptor tools that can reverse the file encryption. The removal guide we have written below is another possible solution. We cannot promise that everything will be back to normal but if you follow its instructions you will have a big chance to at least remove Ooii from your computer.

Remove Ooii Ransomware


Step1
 
 

Before you start with the actual removal of Ooii, it is a good idea to save the URL of this page in the bookmarks section of your browser so that you can easily return to it after completing the next steps in the removal process.

After you have saved the Ooii removal guide to your computer’s bookmarks, we recommend that you restart your computer in Safe Mode. If you need assistance with this, you can refer to the following URL for step-by-step directions.

Then, go to the Windows search field (normally found in the Start menu), type msconfig and press the Enter key on the keyboard.

This will open the System Configuration window on the screen. Once you see it, open the Startup tab and make sure you uncheck any checkmarked Startup items that Ooii has added to the list. Then, after you’re finished, click OK to close the window.

msconfig_opt

WARNING! READ CAREFULLY BEFORE PROCEEDING!

The ransomware infection begins to perform a number of harmful tasks in the background almost immediately after it has invaded your system and taken over the control of it. Therefore, your very next task is to identify and terminate any processes that you consider to be responsible for OoiiX’s actions and behavior.

In order to do so, hit the CTRL, SHIFT, and ESC keys on your keyboard at the same time to open up the Task Manager on your computer. Once you’ve done that, navigate to the Processes tab and scroll through the list of currently running processes until you find something that looks dangerous. As shown on the image below, once you detect a suspicious process, you can right-click on it and select Open File Location:

As soon as you have completed the above, you should use the free virus scanner provided below to check for any malware in the files linked with the selected process:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    If any potentially harmful files are found by the scanner, you must first stop the associated process in Task Manager, which is presently running on your computer. This will allow you to thoroughly remove the dangerous files from their location.

    You can terminate a process by selecting it from the shortcut menu that appears by right-clicking it and then selecting “End Process“.

    Step3

    The computer’s Hosts file is a typical target for malware and sometimes, there could be unauthorized changes in it in case the computer is compromised. Thus, to check it, open your Hosts file and scan for any changes in the Localhost section of the text. If needed, double-check that everything in there is looking good and there is nothing suspicious before moving forward.

    This can be accomplished by first opening a Run dialog box on your computer by simultaneously clicking the Windows Key and the R key on your keyboard, and then pasting the following command into it:

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

    Following your selection of “OK” the Hosts file should appear on your computer’s screen:

    hosts_opt (1)

    If you see any IP addresses that appear suspicious to you, such as those in the image above, you should report them to us by leaving a comment at the bottom of this article. In the event that there is a threat, you will receive a response from a member of our team with recommendations on what to do next.

    Step4

    Ransomware viruses invade your computer’s Registry on a regular basis, adding potentially hazardous files into the system. As a result, in order to completely remove the malware, you must carefully search the Registry for potentially harmful files and delete any that are discovered.

    To access the Registry Editor, type Regedit in the Windows search field and hit Enter. The program will open automatically. Next, open up the Editor’s Find dialog box by pressing the keys Ctrl and F at the same time, and type the name of the ransomware into it. After that, you can click the Find Next button on the right to conduct a search to discover whether any records exist for the specific name you entered seconds ago. You must then remove only the entries that are related with the ransomware from your computer’s registry.

    Attention! When a user is inexperienced and does not know which registry files to delete, they might cause substantial damage to their computer’s operating system. In order to avoid this, it is highly recommended that malware and potentially harmful files be removed from the system and from the registry only with the assistance of a professional anti-malware program.

    Once the registry is clean, we recommend you to also manually check for possibly hazardous files in the following locations on your computer:  

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

    Simply type each of them in the Windows search field and press Enter to open it. Next, look for new files or subfolders with strange names that have been added around the time of the infection. Everything that appears to be out of place should be carefully removed as soon as possible. Again, don’t delete files you are not sure about and use professional software to avoid involuntary system damage. In order to ensure that any malware-created temporary files are removed from the system, select and delete all the temporary files that have been saved in the Temp folder.

    Step5

    How to Decrypt Ooii files

    Those who have been affected by ransomware may have a difficult time regaining access to their files, as this process may necessitate the use of a number of different programs and alternative ways in order to successfully recover their data. That’s why, if you’ve been attacked with ransomware, the first thing you should do is figure out which type of the malware has encrypted your data. If you look at the file extensions that have been assigned to the encrypted files, you will be able to figure out the exact variant very easily.

    New Djvu Ransomware

    STOP Djvu is a new Djvu ransomware variant that is causing trouble on a number of systems globally and is presently the latest Djvu ransomware variant that you should be concerned about. In the case of this particular ransomware has infected you, the filenames of all files that have been encrypted by it will have the extension .Ooii appended to the end of them.

    Decoding STOP Djvu encoded files is a challenging task, but there is a way to get your files back if they have been encoded with an offline key, which is presently the only type of key that can be decrypted. We’ve attached a link to a decryption program that you might find useful with decrypting your data and, in the next paragraph, you will learn how to use it:

    https://www.emsisoft.com/ransomware-decryption-tools/stop-djvu

    Open the URL provided above in your browser and click on the Download button located in the top right corner of the page. This will instantly begin the process of downloading the STOPDjvu.exe file to your computer.

    To open the file, select “run as administrator” and then press the Yes button to confirm. After reading the license agreement and the brief instructions on how to use the application, you can begin the decryption process by clicking on the Decrypt button on the program’s toolbar. Please keep in mind that this decryptor may not be able to decrypt files that have been encrypted using unknown offline keys or online encryption, so note that if your files are unable to be decrypted for any reason. 

    Ooii and other harmful software can be removed from your computer with the use of a professional anti-virus tool, such as the one linked on this page, or a sophisticated online virus scanner. So, don’t hesitate to use these tools and clean your computer if you are unable to remove the infection manually. Should you run into any difficulties while following these instructions, please do not hesitate to post them in the comments section of this article, and we will do our best to assist you.
