This page aims to help you remove Cryptesla. These Cryptesla removal instructions work for all versions of Windows. In recent days we have had numerous inquiries from our Japanese readers about “vvvウイルス”. If you are reading this then you probably already know you are dealing with an extremely dangerous computer virus. Cryptesla is a type of malware called Ransomware and has been closely associated with the VVV extension. Why it is called like that and what are the symptoms?

Cryptesla Ransomware

Cryptesla VVV extension

As you can see on the above image send by one of our readers accompanied by the message “vvvウイルス” a high percentage of your important files would be with some strange extension. The files with the strange extension cannot be opened or made in any way readable. A message in the form of text file or other would appear on your desktop, explaining that you files are encrypted and demanding a certain sum in exchange for a decryption key.

Now you know you are dealing with Ransomware. It also means that you have a very serious problem on your hands and some tough decisions await you if you are to salvage any of your files, and as previously mentioned and as evidenced by the “vvvウイルス” questions this virus has targeted specifically Japanese users.

Should you pay the demanded ransom?

That is probably the question that first springs to an affected user’s mind. And fairly so, no one wants to abandon all his information go to waste. It is always a personal choice and preference in situations like this but it is our strong recommendation you abstain from paying any sum as a ransom. No matter what the explanatory note has indicated this is neither the best solution nor the safest for you.

The first concern that you should consider when deciding whether to yield to the ransom demands is that you are in fact dealing with criminals. It is as simple as that – these people are cyber criminals, so you can never know whether they will keep their end of the bargain after you pay them or instead they will demand more money instead of providing a key for your locked files. What can be sure of though is that your money will be in fact encouraging the perpetrators to continue producing and improving their ransomware.

We should warn you here – below you will find described methods and instructions how to get your files back. There is no guarantee that they will work for you at all and whether you will get all your files back or only a part of them. This is hugely depending on how much time has passed since you discovered that you have been compromised by Cryptesla. Don’t lose hope, there is absolutely a chance you might recover your files. Also be calm in the knowledge that the methods we are describing will not mess with the encrypted files and they will not be deleted by the virus, contrary to what the warning message might be saying.

How Cryptesla operates?

Almost all Ransomware threats access the victim’s computer through a previously infiltrated Trojan horse. Once on the inside the ransomware virus will make a “list” of your personal and most often accessed files. After that it will begin encrypting the selected files transforming them in the way you have probably discovered in dismay. When the encryption of a file is completed the original file is being deleted and all that remains is the encrypted copy that can be decrypted only with the help of a specific key used in the encryption. Basically this is what you will be paying for according to the hackers. The encryption key.

We are going to offer you an alternative though, but first you need to rid yourself of the virus!

Cryptesla Virus Ransomware Removal


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

This is just the first preparation.


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 detection tool is free. To remove the infection, you'll need to purchase its full version. More information about SpyHunter and steps to uninstall.

The first mandatory thing is to allow you to see Hidden Files and Folders. Each version of Windows does this slightly differently.

  • I repeat – it’s extremely important you do this. Cryptesla may have hidden some of its files and you need to see them to delete them.

Hold the Start Key and R againbut this time copy + paste the following and click OK:

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

A .txt file will open – don’t type or change it. If you are hacked and someone has access to your PC, there will be a bunch of other IPs connected to you at the bottom. This is what a hosts file looks like:

hosts_opt (1)

If there are a bunch of strange IPs connecting to you below “Localhost” you may be hacked, and it’s best to ask us in the comments for directions.


Right click on each of the malware processes separately and select Open File Location. Also, End the process after you open the folder. Just to make sure we don’t delete any programs you mistakenly took for a malware, copy the folders somewhere, then delete the directories you were sent to. There’s a good chance Cryptesla is hiding somewhere in here.


Dear reader, you are at a very important point in the removal process. The steps are pivotal for successfully removing Cryptesla from your system. At the same time there is a high chance that if you make even a small mistake that might lead to pretty grave consequences. You will be asked to operate with important system files, so in case of a mess-up there is pretty high chance that your device might be severely damaged or rendered completely inoperative.

Only continue if you feel absolutely confident in your ability to perform the tasks exactly as outlined by us. If you have any doubts you simply don’t want to take any chances we recommend you think about downloading and installing a professional program that will scan your hard drives and remove the malware completely and automatically. We feel this is the best choice especially for users that are not experienced in manual virus removal.


Right click on each of the virus processes separately and select Open File Location. Also, End the process after you open the folder. Just to make sure we don’t delete any programs you mistakenly took for a virus, copy the folders somewhere, then delete the directories you were sent to.


Take a look at the following things:

Type msconfig in the search field and hit enter: you will be transported to a Pop Up window.


Go in the Startup tab and Uncheck entries that have “Unknown” as Manufacturer.

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If you can’t find them this way, look in these directories, and delete/uninstall the registries manually:

    1. Type regedit in the Windows Search Field. Search for the ransomware (try typing its name) in your registries and delete anything with that name. But be extremely careful – if you delete the wrong thing here, you can damage your system.
    2. Type %temp% in the Windows Search Field and delete all the files in the folder you are transported to.

How to Decrypt files infected with Cryptesla

There is only one known way to remove this virus successfully, barring actually giving in the to the demands of the people who created the virus – reversing your files to a time when they were not infected.

There are two options you have for this:

The first is to do a full system restore. This can take care of the file extension for you completely. To do this just type System Restore in the windows search field and choose a restore point. Click Next until done.

system restore_opt

Your second option is a program called Recuva

Go to the official site for Recuva and download it from there – the free version has everything you currently need.

When you start the program select the files types you want to recover. You probably want all files.

Next select the location. You probably want Recuva to scan all locations.

Now click on the box to enable Deep Scan. The program will now start working and it may take a really long time to finish – maybe even several hours if your HDD is really big, so be patient and take a break if necessary.

You will now get a long list of files to pick from. Select all relevant files you need and click Recover.
