Virus-encoder ransomware removal instructions
What is Virus-encoder?
Virus-encoder (also known as GetCrypt) is the name of ransomware-type program that is designed by cyber criminals. They use programs of this type to encrypt files stored on people's computers and to keep them encrypted (locked) unless a decryption tool is purchased (ransom is paid). Virus-encoder was discovered by GrujaRS, this ransomware mimics another program of this type which is called Cerber. It creates a text file (ransom note) named "# DECRYPT MY FILES #.txt" and renames all encrypted files by adding an extension that contains four random letters. For example, if a file is named "1.jpg", then Virus-encoder will change it to "1.jpg.ELSH" and so on. This ransomware also changes its victim's desktop wallpaper. Once installed, it also runs a malicious process in the Task Manager, it is named "Tky If Dos".
Virus-encoder also has a feature which is rather unusual for regular ransomware infections. It is designed to try to connect to available network shares. If these networks are password-protected, Virus-encoder attempts to brute-force these logins/passwords by using a list of hard-coded login/password entries. To simplify, Virus-encoder attempts to "guess" the login information by entering various commonly used logins/passwords (e.g., admin:admin, root:root and similar). If the brute force is successful, Virus-encoder encrypts shared files as well. "# DECRYPT MY FILES #.txt" explains Virus-encoder's victims that their computers are infected and all files are encrypted using a strong cryptography algorithm. It says that it is impossible to decrypt files without using a particular decryption tool and key. To get it, victims are encouraged to contact cyber criminals via email@example.com. There is another email provided too (firstname.lastname@example.org), it can be found on a changed wallpaper. One of these emails has to be used to send Virus-encoder's developers the "encrypted_key.bin" file that is placed in "%appdata%" folder. There are no other details provided, it is very likely that these cyber criminals provide them after they are contacted. One way or another, we do not recommend to trust any ransomware developers and pay them a ransom (buy decryption tools/keys from them). Most of them do not send their victims the tools/keys that supposed to be used to decrypt encrypted files. Unluckily, ransomware-type programs encrypt files using strong encryption algorithms. Simply said, encrypted files can be decrypted using tools that only particular ransomware's developers have. Typically, the only way to restore files without having to pay for a decryption tool/key is to restore them from a data backup.

There are many other programs that are similar to Virus-encoder out there, here are a few examples: TOR13, india2lock, and ge0l0gic. Typically, these malicious programs are designed to encrypt data and display ransom demanding messages/force victims to buy decryption tools. The main differences between them usually are the price of the decryption and a cryptography algorithm (symmetric or asymmetric) that is used to encrypt data. Unfortunately, most encryptions caused by ransomware are impossible to decrypt without using tools that only cyber criminals can provide, unless these programs have some bugs, flaws, are not fully developed. For this reason, we recommend to always have a data backup created and to store it on a remote server or unplugged storage device.
How did ransomware infect my computer?
It is known that cyber criminals spread this ransomware by using the RIG Exploit Kit. Crooks inject malicious scripts into various websites which, when visited, search for system vulnerabilities and inject malware by exploiting found vulnerabilities. Typically, malicious programs are proliferated through spam campaigns, untrustworthy software download tools/sources, fake software updating tools, trojans and software cracking tools. Spam campaigns can be used to spread computer infections through emails. Cyber criminals send emails that contain malicious attachments or web links that lead to them. They attach Microsoft Office documents, archive files (such as ZIP, RAR), PDF files, executable files and hope that someone will open them. If opened, these files download and install high-risk malware like ransomware. Untrustworthy software download sources can be used to spread malicious programs too. Some examples of sources of this kind are Peer-to-Peer networks (torrent clients, eMule and so on), free file hosting, freeware download websites, various questionable pages and other similar channels. Cyber criminals use them to trick people into downloading and installing malware by themselves. They achieve it by presenting malicious files as legitimate. Unofficial/fake software updaters can be used to proliferate malware too. People who use them often cause downloads and installations of malicious programs instead of updating programs. These tools can be used to exploit outdated software's bugs, flaws as well. Trojans are malicious programs that are designed to cause chain infections. However, they must be already installed. Various 'cracking' tools are used to bypass activation of paid software, however, they often are the main reasons behind computer infections too. Simply said, there are many cyber criminals who design these tools to download and install malware.

To eliminate Virus-encoder virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To avoid downloads and installations of malware, do not open attachments (or website links) that are presented in irrelevant emails, especially if they are received from unknown, suspicious addresses. Update installed programs/operating system using implemented functions or tools provided by official developers only. Third party/unofficial tools should be trusted for that. Software should be downloaded from official websites and using direct download links. It is not recommended to use any other sources for that. Furthermore, usage of software cracking tools is a cyber crime. Besides, they often are designed to spread various viruses. Have a reputable anti-spyware or anti-virus software installed and make sure that it is always enabled (active). If your computer is already infected with Virus-encoder, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
