Tuis ransomware is the infection that triggers the file-locking procedure before asking for money

Tuis file virus – the ransomware that relies on encryption and cryptocurrency payment demands. The infection is marking encoded files with .tuis appendix, hence the name of the virus. However, these are not the only functions of the threat. It can run in the background causing various damage and injecting processes or stopping programs that run on the machine already.
The threat is focused on scaring people into transferring money, so the _readme.txt ransom note is designed to list various false claims for the victims and make them believe that the infection is major and that there is no way back except paying the demanded sum to Tuis ransomware creators.
These criminals who develop and operate cryptovirus threats are considered one of the most dangerous criminals and cyber threat creators, so any contact with them via email or other sources can trigger more issues instead of providing a good solution for affected files. Tuis file virus is nothing but a file locker that is creating a reason for this extortion[1] with the encryption procedure.
General information on ransomware
This is the version of the known and existing file-locker virus family that is releasing variants weekly. This infection is triggering malicious processes on the machine, so the Tuis ransomware virus can run for longer. These threats can also rely on other infections like trojans or malware to ensure that processes cannot be interrupted.

| Repair | The infection causes major issues with the machine, so FortectIntego helps to repair the damage |
There are tons of issues caused by the virus, even though the main goal is to trick people into transferring money when the ransom note claims and the discount offer seem convincing enough. There is no need to even contact people behind the threat, however. Experts[2] always recommend ignoring these threats.
Even if you think that there are no other options for the recovery of files, it is not a good idea to pay or write people behind the infection. Tuis ransomware virus creators might receive money and disappear without providing you with the help you need. The test decryption and a 50% discount should not encourage you to believe them either.
Removing the infection
Tuis file virus is not the product of white hat hackers or any people that could be trusted. The infection is far from simple since it is coming from the operators of the Djvu ransomware virus. You should rely on these details, research, and detection rates[3] and remove the threat from your device.
The particular tool designed to remove viruses and possibly malicious pieces can help terminate the infection and stop the active virus from affecting the machine. When you remove Tuis ransomware, you can ensure that encryption cannot be launched again. Make sure to eliminate the infection, so file recovery can be achieved safely.
Anti-malware tools like SpyHunterCombo Cleaner or MalwarebytesMalwarebytes can scan the machine and indicate all potentially malicious pieces or files, and programs when checking the machine. The threat can be indicated as the dangerous piece and properly removed, stopped from accessing the data on the infected computer. Make sure to double-check to be sure that the Tuis file virus is no longer running.
Keeping the infection on the machine while files get recovered might lead to permanent damage to files and second rounds of encryption. Do not hurry into the file recovery, and note that infection removal is not the same as decryption of the virus or data restoring programs. Remove the active virus, recover the damage that Tuis file virus left and then move to alternate options for recovery of the data.

Recovering system functions after the infection
Once a computer is infected with malware, its system is changed to operate differently. For example, an infection can alter the Windows registry database, damage vital bootup and other sections, delete or corrupt DLL files, etc. Once a system file is damaged by malware, antivirus software is not capable of doing anything about it, leaving it just the way it is. Consequently, users might experience performance, stability, and usability issues, to the point where a full Windows reinstall is required.
Therefore, we highly recommend using a one-of-a-kind, patented technology of FortectIntego repair. Not only can it fix virus damage after the infection, but it is also capable of removing malware that has already broken into the system thanks to several engines used by the program. Besides, the application is also capable of fixing various Windows-related issues that are not caused by malware infections, for example, Blue Screen errors, freezes, registry errors, damaged DLLs, etc.
- Download the application by clicking on the link above
- Click on the ReimageRepair.exe

- If User Account Control (UAC) shows up, select Yes
- Press Install and wait till the program finishes the installation process

- The analysis of your machine will begin immediately
- 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.

What else can be done?
Tuis ransomware demands money, and the ransom note _readme.txt claims that the transfer of at least $490 can salvage those encrypted files. However, the infection creators are financially motivated, and your belongings are not a topic of worry for them. Paying is not a solution.
Tuis ransomware virus is not decryptable. The infection comes to from a powerful family of threats, so researchers cannot come up with solutions this quickly. Decryption is the only way that your files can be recovered, but there are no options for that right now. You can still rely on alternate methods.
The best option for the encoded could be data backups stored on other devices and networks like the cloud. Tuis file virus can affect all connected devices, so make sure to store backups on devices that are not connected to the computer at all times. Universal tools might also sometimes help, but this is the new version.
Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.
While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.
Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important while dealing with this situation:
- Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
- Only attempt to recover your files using this method after you perform a scan with anti-malware software.
Install data recovery software
- Download Data Recovery Pro.
- Double-click the installer to launch it.

- Follow on-screen instructions to install the software.

- 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.

- 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.

Tuis ransomware virus can damage other parts of the machine besides locking those commonly used files like images, audio, video files, and documents. The infection is coming after 500 other versions that are identical, and creators do not bother to alter the coding or other functions of the infection at all.
These infections can scare the living out of people, but this marks how important it is to keep backups of your data. Infections like Tuis ransomware can be considered one of the most dangerous, so the sooner you remove the virus, the better because you can avoid further damage and major changes.
