Toec ransomware removal instructions
What is Toec?
Toec is ransomware that belongs to the Djvu ransomware family. Typically, people who have computers infected with malware like Toec cannot access or use their files, since these programs encrypt data with strong encryption algorithms. In most cases, the only way to decrypt files is to use decryption tools and/or keys, which can only be purchased from the cyber criminals who designed the ransomware. Therefore, victims are forced to pay ransoms. Toec renames encrypted files by appending the ".toec" extension. For example, "1.jpg" becomes "1.jpg.toec". It also creates a ransom message within the "_readme.txt" text file.
Victims of Toec ransomware are offered free decryption of one file, which can be sent to developers via the firstname.lastname@example.org or email@example.com email address. If contacted within the first 72 hours of encryption, they offer the decryption tool and key at $490. After this, the cost increases to $980. Therefore, victims are encouraged to send an email immediately. The ransom message states that it is impossible to decrypt files without tools that can be provided only by Teoc developers. Unfortunately, this is accurate - most ransomware-type programs encrypt files with strong algorithms, and only the cyber criminals who designed the specific ransomware have valid decryption tools. Typically, the only way to avoid data loss without having to pay a ransom is to restore files from a backup. Note that cyber criminals can never be trusted. Even if victims pay, they often receive no tools to decrypt their files. Even if ransomware is removed from the system, all files remain encrypted - removing ransomware only prevents further encryption.

Most ransomware-type programs prevent victims from accessing their files by encryption and create ransom messages that contain instructions about how to pay the ransom. Some examples of other ransomware programs include Asus, Decrypme, and 2Hamlampampom. Main differences are cost of decryption tool and/or key and cryptographic algorithm (symmetric or asymmetric) used to lock data. In most cases it is impossible to decrypt files without tools held only by the developers of ransomware, unless the ransomware is not fully developed (has bugs, flaws, and so on). Therefore, have your data backed up and keep it on a remote server and/or unplugged storage device.

How to protect yourself from ransomware infections
If an email is received from an unknown, suspicious address, is irrelevant and contains an attachment, ignore it and do not open files or links included. It is safer to download all files and programs from official, trustworthy websites and via direct links. Various third party downloaders (and installers), dubious pages, Peer-to-Peer networks (torrent clients, eMule), and other similar sources should not be trusted. They are often used to distribute malicious programs. Furthermore, update software using tools or implemented functions provided by official developers. Do not use third party tools. Note that software 'cracking' programs are illegal and often cause high-risk computer infections. Do not use them. Keep computers and operating systems safe by having reputable antivirus or anti-spyware software installed. Scan the system with it regularly. If your computer is already infected with Toec, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

IMPORTANT NOTE! - As well as encrypting data, ransomware-type infections from the Djvu malware family also add a number of entries to the Windows "hosts" file. The entries contain URLs of various websites, most of which are related to malware removal. This is done to prevent users from accessing malware security websites and seeking help. Our website (PCrisk.com) is also on the list. Removing these entries, however, is simple - you can find detailed instructions in this article (note that, although the steps are shown in the Windows 10 environment, the process is virtually identical on all versions of the Microsoft Windows operating system).
Screenshot of websites added to Windows hosts file:
There are currently two versions of Djvu ransomware infections: old and new. The old versions were designed to encrypt data by using a hard-coded "offline key" whenever the infected machine had no internet connection or the server was timing out/not responding. Therefore, some victims were able to decrypt data using a tool developed by cyber security researcher, Michael Gillespie, however, since the encryption mechanism has been slightly changed (hence the new version, released in August, 2019), the decrypter no longer works and it is not supported. If your data has been encrypted by an older version, you might be able to restore it with the another tool developed by Emsisoft and Michael Gillespie. It supports a total of 148 Djvu variants and you can find more information, as well as download link and decryption instructions on the Emsisoft's official web page.

Additionally, Emsisoft is now providing a service that allows data decryption (again, only if it was encrypted by Djvu variants released before August, 2019) for those victims who have versions of files before and after encryption. Victims simply upload the original and encrypted file to Emsisoft's Djvu decryption web page and download the aforementioned decryption tool (the download link will be provided after uploading files). Note that file processing may take some time, so be patient. Note that the system must have an internet connection during the entire decryption process, otherwise it will fail.
