HORSELIKER ransomware removal instructions
What is HORSELIKER?
HORSELIKER belongs to the Phobos ransomware family, the person who discovered it is Raby. Like most ransomware-type programs, HORSELIKER is designed to encrypt files with a strong encryption algorithm. In order to be able to decrypt encrypted files victims of HORSELIKER have to pay its developers a ransom. This ransomware renames all encrypted files, it changes their filenames by adding victim's ID, email address and the ".HORSELIKER" extension. For example, HORSELIKER renames a file named "1.jpg" to "1.jpg.id[1E857D00-2374].[firstname.lastname@example.org].HORSELIKER", and so on. Also, it creates a text file named "info.txt" and "info.hta" file that, if opened, displays ransom note in a pop-up window.
To get a decryption tool (decryption key or/and program) victims have to contact cyber criminals via email@example.com email address or Jabber client (firstname.lastname@example.org account). Either way, decryption tool will be provided only after a payment which must be done using cryptocurrency (Bitcoin). It is stated that price of a decryption depends on how fast victims will contact cyber criminals who designed this ransomware. They offer to decrypt 1-3 files for free, however, only the files that do not contain any valuable information. Decrypted files can be sent to them via email or Jabber. Also, HORSELIKER's developers encourage their victims not to rename any of the encrypted files or try to decrypt them using some third party tools because it might cause permanent data loss. To sum up, victims have to contact these cyber criminals, pay them a ransom and then wait until they will send a decryption tool. However, it is very likely that they will not send it. Quite often ransomware developers who get paid start to ignore their victims, in other words, people who trust them get scammed. Unfortunately, there are no other tools that could be capable of decrypting files encrypted by HORSELIKER for free. In most cases the only way to recover files without losing money and risking to be scammed is to restore them from a created backup.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
HORSELIKER is not the only ransomware, there are many other programs of this type. Some examples are Bora, CASH and Sapphire. What most of these malicious programs have in common is that they encrypt data create files that contain instructions on how to pay a ransom. Main differences usually are cryptographic algorithm (symmetric or asymmetric) that is used to encrypt data and price of a decryption. One way or another, most encryptions cannot be decrypted without interference of cyber criminals. It is possible to avoid that only if ransomware is still in a development state, has some bugs, flaws. That is why we recommend have data backed up and to store it on a remote server or unplugged storage device.

How to protect yourself from ransomware infections?
We strongly recommend not to open attachments (or web links) that are received from some unknown, suspicious address, or/and presented in irrelevant emails. Also, it is important to keep installed software up to date. However, the only safest way to achieve it is to update it with implemented functions or tools that are designed by official software developers. Furthermore, we advise to download software only from official websites and avoid using third party downloaders (or installers), Peer-to-Peer networks and other tools that we mentioned in the previous paragraph. Installed programs should not be activated through unofficial ('cracking') tools. They are not legal and often infect computers with high-risk malware. We also recommend to have a reputable anti-virus or anti-spyware software installed and scan a computer with it regularly. If your computer is already infected with HORSELIKER, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining HORSELIKER ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of HORSELIKER are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as HORSELIKER ransomware.
Note that Windows 10 Fall Creators Update includes "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default this feature automatically protects files stored in Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here's more information on how to get this update and add additional protection layer from ransomware infections.
