In this guide I will try to help you remove Toec virus for free. As bonus I will assist you in decoding your crypted files.

What is “Toec”?

Toec can be correctly identify as a ransomware infection.
Ransomware is a specific kind of virus that crypted your documents and then forces you to pay for them. Note that DJVU (aka STOP) ransomware family was first revealed and analyzed by virus analyst Michael Gillespie1.

Toec is basically similar to other representatives of the same family: Meka, How, Craw. It crypted all common file types. Hence, users cannot use the your documents . Toec adds its particular “.toec” extension into all files. For example, the file “video.avi”, will be amended into “video.avi.toec”. As soon as the encryption is successfully accomplished, Toec drops a specific file “_readme.txt” and drop it into all folders that contain the modified files.

This text asking payment is for restore files via decryption key:

Toec virus message

The scary alert demanding from users to pay the ransom to decrypt the compromised data contains these frustrating warnings

The cryptography algorithm used by Toec is AES-556. So, if your files got encrypted with a specific decryption key, which is totally unique and there are no other copies. The sad reality is that it is impossible to restore the information without the unique key available.

In case if Toec worked in online mode, it is impossible for you to gain access to the AES-556 key. It is stored on a distant server owned by the frauds who promote the Toec infection.

For receiving decryption key the payment should be $980. To obtain the payment details the victims are encouraged by the message to contact the frauds by email ([email protected]), or via Telegram.

Do not pay for Toec!

Please, try to use the available backups, or STOPDecrypter tool

_readme.txt file also indicates that the computer owners must get in touch with the Toec representatives during 72 hours starting from the moment of files where crypted. On the condition of getting in touch within 72 hours users will be granted a 50% rebate, thus the ransom amount will be minimized down to $490). However, stay away from paying the ransom!

I definitely recommend that you do not contact these crooks and do not pay. The one of the most real working solution to recover the lost data – just using the available backups, or use STOPDecrypter tool.

The peculiarity of all such viruses apply a similar set of actions for generating the unique decryption key to recover the ciphered data.

Thus, unless the ransomware is still under the stage of development or possesses with some hard-to-track flaws, manually recovering the ciphered data is a thing you can’t really perform. The only solution to prevent the loss of your valuable data is to regularly make backups of your crucial files.

Note that even if you do maintain such backups regularly, they ought to be put into a specific location without loitering, not being connected to your main workstation.

For instance, the backup may be kept on the USB flash drive or some alternative external hard drive storage. Optionally, you may refer to the help of online (cloud) information storage.

Needless to mention, when you maintain your backup data on your common device, it may be similarly ciphered as well as other data.

For this reason, locating the backup on your main device is surely not a wise idea.

How I was infected?

Toec has a various methods to built into your system. But it doesn’t really matter what way was used in your case.

Toec infection attack

Toec attack following a successful phishing attempt.

Nevertheless, these are the common leaks through which it may be injected into your PC:

  • hidden installation along with other apps, especially the utilities that work as freeware or shareware;
  • dubious link in spam emails leading to the Toec installer
  • online free hosting resources;
  • using illegal peer-to-peer (P2P) resources for downloading pirated software.

There were cases when the Toec virus was disguised as some legitimate tool, for example, in the messages demanding to initiate some unwanted software or browser updates. This is typically the way how some online frauds aim to force you into installing the Toec ransomware manually, by actually making you directly participate in this process.

Surely, the bogus update alert will not indicate that you are going to actually inject the Toec ransomware. This installation will be concealed under some alert mentioning that allegedly you should update Adobe Flash Player or some other dubious program whatsoever.

Of course, the cracked apps represent the damage too. Using P2P is both illegal and may result in the injection of serious malware, including the Toec ransomware.

To sum up, what can you do to avoid the injection of the Toec ransomware into your device? Even though there is no 100% guarantee to prevent your PC from getting damaged, there are certain tips I want to give you to prevent the Toec penetration. You must be cautious while installing free software today.

Make sure you always read what the installers offer in addition to the main free program. Stay away from opening dubious email attachments. Do not open files from the unknown addressees. Of course, your current security program must be always updated.

The malware does not speak openly about itself. It will not be mentioned in the list of your available programs. However, it will be masked under some malicious process running regularly in the background, starting from the moment when you launch your PC.


The message by the Toec ransomware states the following frustrating information:
