The Ransomware infections are very dangerous computer threats, feared by many web users. Their representatives have increased in numbers in the last couple of years, and more and more unsuspecting internet users have been getting targeted by new advanced infections of this kind. One of these latest versions of Ransomware is called Tuid. This threat is a member of the so-called cryptovirus subgroup. Typically, this infection harms its victims by applying a special encryption to their files, without their knowledge. This allows the hackers behind the threat to blackmail the victims for the access to their personal information. Unfortunately, the applied file encryption is typically so hard to remove that the victims often see no other choice but to pay the requested ransom money, hoping to get back their access to the locked files.

Fortunately, there are some alternatives that may help handle such a situation without paying the ransom. If you stay with us, you’ll find out more about them. because down below we have published a comprehensive removal guide to assist you with the removal of Tuid deal. The removal guide includes manual methods of removal of the cryptovirus, and a professional removal tool, as well as guidelines on how to potentially recover some of your encrypted files without sending money to the hackers.

The Tuid virus

The Tuid virus is a dangerous file encrypting threat. If you have the Tuid virus on your computer, you should carefully explore the methods of dealing with it.

The Tuid virus will encrypt your files

Most Ransomware viruses, such as Tuid, Udla, Voom have a set of features that guarantee that they infect the system secretly, and execute the malicious action for which they were developed. Their stealthiness is one of the key features. Such infections can prevent most antivirus programs from detecting them. The reason for this is that the file encryption they use is a method that is in not inherently malicious or dangerous on its own. It simply makes the files located on the system inaccessible without a special decryption key. The problem is the only people who have that key are the cybercriminals behind the Ransomware, and they blackmail you for the said key.

The .Tuid file extension

The .Tuid file extension is a special encoding that prevents the affected files from being opened and appears after the encryption gets completed. If you see the .Tuid file extension on some of your files, it means you won’t be able to open those files.

We frequently get asked by a lot of Ransomware victims about what the possible courses of action are once they’ve been infected, and the malware has applied its encryption to all of their pictures, videos, archives, and other files. Unfortunately, we have to be honest here, and say that nothing can guarantee that your information will be accessed again. If you decide to pay the hackers, they may send you a decryption key, but they may also refuse to do so. Not to mention that the key may not work, even if you get one.

So, with this in mind, trying other options, like those mentioned in the removal guide below, is a good start. Another option is to retrieve your files from external disk copies, or cloud storage copies, or maybe from system backups, whenever this is possible. However, it is important to remove Tuid from the system before you start any file recovery attempts. This will enable you to use your machine normally, and safely connect backups sources without them getting encrypted.

Remove Tuid Ransomware


Step1

We recommend rebooting the infected machine in Safe Mode before moving on to the next steps in this guide because dealing with a ransomware infection can be a difficult undertaking that may include meddling with a lot of system files and processes. By running only the most essential processes and apps, Safe Mode allows you to identify and eliminate any suspicious processes and programs without wasting your time. You may find detailed instructions on how to reboot in Safe Mode at this URL.

Prior to rebooting, however, be sure to bookmark this removal guide in your browser, so that you can return to it and complete the rest of the steps below.

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

As soon as a ransomware infection such as Tuid sneaks inside the computer, it immediately starts to run malicious processes in the background. You may not be aware of these processes but, in order to eliminate Tuid, you must locate and end them as soon as possible, and delete all the files related to them.

To do that, press Ctrl, Shift and ESC on your keyboard and look through the list of running Processes in the Windows Task Manager. Right-click on a process that you think is dangerous and select Open File Location from the quick menu.

Next, use the free virus scanner below to scan the files associated with that process for malware:

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.

    Before trying to remove any dangerous files discovered by the scanner, you must stop the corresponding process in Task Manager. To do this, right-click on the process and then choose “End Process” from the quick menu. Once the process has been stopped, delete the harmful files form their location.

    Step3

    When a computer is infected with malware, the Hosts file is likely to be altered. Look for any odd IP addresses under “Localhost” in your Hosts file to see if anything has been modified.

    Press the Windows Key and R key on your computer at the same time and copy the following command in the Run box to open the Hosts file:

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

    When you click OK, the following file should appear on your screen:

    hosts_opt (1)

    Please let us know in the comments below if you notice any suspicious IP addresses under Localhost in your file. As soon as we verify the IP addresses, we’ll get back to you with recommendations on what to do next.

    Next, in the Windows search field (normally found in the Start menu), type msconfig and open the System Configuration app on the screen. In the Startup tab, search for any startup items that could be related to Tuid and remove their checkmark to disable them.

    msconfig_opt

    If your system has been infected with ransomware, you may find dangerous files in the Registry. Therefore, a registry scan is essential in order to remove the infection, because if these dangerous files are not deleted, they may help the ransomware re-install itself and continue to cause chaos on your system. 

    To search the registry and make changes to it, you need to open the Registry Editor by typing Regedit in the Windows search field and pressing Enter. Next, once in it, press Ctrl and F at the same time to access the Editor’s Find dialog box. After that, type the malware’s name in the Find box. To search for records with that name, you should click the Find Next button. 

    Attention! Only ransomware-related files should be deleted from the registry. Inexperienced users can cause a lot of harm to the system if they delete files belonging to legitimate programs and the system. To avoid this risk, please use a professional anti-malware application to delete the malware and any potentially dangerous files from the registry. 

    After ensuring that the registry is clean from ransomware-related entries, manually search the following five locations for potentially harmful files. Simply type each of them exactly as it is shown (including the percentage symbol) in the Windows search field and click Enter to open them.

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

    If needed, do a thorough online investigation of any new files or subfolders with strange names in any of the locations before deleting them. In the end, select and delete all the temporary files saved in Temp to remove any malware-created files from the system.

    Step5

    How to Decrypt Tuid files

    A wide range of tools and alternative solutions may be needed for ransomware victims to restore access to their files. The first thing that it’s important to know before you can take any further action is which ransomware variant has encrypted your data. The file extensions attached to the encrypted files can give you this information, so look at the extensions of your files first.

    New Djvu Ransomware

    There has been an outbreak of Stop Djvu, a new variant of the Djvu ransomware, which has infected numerous systems around the world. Files encrypted with this threat are given the .Tuid extension at the end of the filename. STOP Djvu files encrypted with an offline key can be decrypted with the help of the decryption application, a URL to which you can find below: 

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

    Clicking the “Download” button in the upper right corner of the page will allow you to download the decryption program. The download of STOPDjvu.exe should begin immediately. 

    If you choose “run as administrator” and then press the Yes button, the file will open. To begin decryption, simply click on the Decrypt button after reading the license agreement and the program’s instructions. It is important to note that this decryptor does not support files encrypted using unknown offline keys or online encryption, so if your files cannot be decrypted, this may be one of the reasons. 

    In order to effectively recover your files, you must first remove the ransomware from the infected PC. If you use a professional anti-virus program or a powerful free online virus scanner like those found on this page, you can easily remove Tuid and other malware from your computer.
