This page aims to help you remove Touhou Ransomware for free. Our instructions also cover how any Touhou file can be recovered.

If your computer has recently gotten infiltrated by a virus program that goes under the name of Touhou, we highly recommend you read the following article within which you’d find some useful and important information regarding the main characteristics of this malicious software threat. In addition, at the bottom of the article, we have also added a manual guide which we have put together in order to help those who need help against this noxious piece of malware. While we cannot guarantee that the instructions from the guide will be effective in your case, we still believe that giving it a try is your best possible course of action at this moment if Touhou Ransomware has indeed made its way inside your system

Ransomware

Touhou belongs to the Ransomware cryptovirus category – a malware group that uses advanced encryption algorithms to render the files of the targeted users inaccessible. The data itself doesn’t get damaged but since usually the only thing that can unlock it is a special key that only the hackers have, the user wouldn’t be able to open any of their files that have been encrypted by the Ransomware. If the victim values their locked-up data and needs to regain their access to it, they’d need to make a payment to the cyber criminals who are responsible for the attack. Such blackmailing schemes using Ransomware viruses have become extremely common throughout the past several years and will likely not go away for quite some time. That is why, it is of utmost importance that all users know how to protect their devices and data from such malicious threats. One thing to note with regards to Ransomware cryptoviruses like Touhou is that those are currently some of the most advanced and thought-out forms of malware which means that oftentimes there might be no effective way to manually handle with an attack by them. We already mentioned that even our guide might not be enough to enable you to deal with Touhou. Although security experts and protection software developers are constantly trying to come up with new ways to stop the rapidly increasing danger of Ransomware infections, hackers still seem to be several steps ahead.

Touhou Ransomware Removal


 

Step1

Some of the steps will likely require you to exit the page. Bookmark it for later reference.

Reboot in Safe Mode (use this guide if you don’t know how to do it).

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous.

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.

Step3

Hold the Start Key and R –  copy + paste the following and click OK:

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

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:

msconfig_opt

Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

  • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.

Step4

WARNING!
To remove parasite, you may have to meddle with system files and registries. Making a mistake and deleting the wrong thing may damage your system.
Avoid this by using SpyHunter - a professional Parasite removal tool.

Keep in mind, SpyHunter’s malware & virus scanner is free. To remove the infection, you'll need to purchase its full version. More information about SpyHunter and steps to uninstall.

Type Regedit in the windows search field and press EnterOnce inside, press CTRL and F together and type the virus’s Name. 

Search for the ransomware  in your registries and delete the entries. Be extremely careful –  you can damage your system if you delete entries not related to the ransomware.

Type each of the following in the Windows Search Field:

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

Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!

How to Decrypt Touhou files

We have a comprehensive (and daily updated) guide on how to decrypt your files. Check it out here.

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!

Reasons why Ransomware is so devastating

Something important that you might have already realized is that Ransomware infections typically go unnoticed by neither the user nor their antivirus program. The reason for this lies in the use of the encryption process that those cryptoviruses are known for. Typically, encryption isn’t a harmful process and won’t cause any damage to the data that’s supposed to get encrypted. It’s just that the files get put under an extra layer of protection that doesn’t allow unauthorized access. However, when this process is used normally, the person who encrypts the data is supposed to be its owner and respectively, the one who holds the key for accessing it. Obviously, when encryption occurs due to a Ransomware infection, this is not the case – the actual user doesn’t have the key and is actually blackmailed into paying for it. However, as we already said, encryption processes aren’t inherently damaging which means that a lot of antivirus programs out there would not detect anything wrong happening inside the PC system and would thus allow the Ransomware to fully carry out its insidious task.

Typically, the user is informed about the ransom demand right after the encryption has been completed – a notepad file gets generated on a visible place or a pop-up notification gets displayed on the user’s screen. Instructions on how to execute the payment are provided within the said notepad/pop-up message. Here, we must mention that although the payment option might seem like a possible way out of this, especially if the files are highly-important or if the required payment isn’t that high, it is not an advisable course of action due to the simple fact that the hacker could always decide to withhold and not send it to you even if you’ve paid the money. The examples of this happening to Ransomware victims are numerous so make sure to take this into consideration before making any rash decisions.

Protection against Ransomware

You must realize that the main reason why most malware infections occur is due to a user mistake. Clicking on a shady link or file attachment from a spam e-mail/Facebook message, interacting with a fake add or launching a fake update request, visiting illegal sites and downloading questionable software. The list goes on and on and the only truly effective way to protect your machine would be to stay on your guard when online and avoid anything that looks fishy. One other highly-important tip that can help you save your files in the instance of an infection by a virus such as Touhou would be to always make sure that your most important data files have been copied and saved on a backup location where no virus could reach them.
