Vhd ransomware removal instructions
What is Vhd?
Vhd ransomware was discovered by Jirehlov Solace. Typically, software of this type is designed to encrypt victims files, rename them and create and/or display some ransom note or multiple notes. This ransomware renames encrypted files by appending the ".vhd" extension to their filenames. For instance, it renames "1.jpg" to "1.jpg.vhd", and so on. It changes file icons too. Vhd creates a ransom note which is a text file named "HowToDecrypt.txt".
As explained in the "HowToDecrypt.txt" text file, the only way for victims to get their files back (decrypt data) is by using a unique decryption key. Its price depend on how fast victims will write Vhd's developers an email to email@example.com or firstname.lastname@example.org. It is mentioned that after three days decryption will become more complicated, however, it is not explained why. Either way, cyber criminals behind Vhd encourage victims to contact them as soon as possible. Typically, victims who contact ransomware developers receive instructions on how to pay a ransom/purchase a decryption software and/or key. As a rule, cyber criminals insist to be paid in Bitcoins or some other cryptocurrency. In one way or another, most of the times victims cannot decrypt their files without tools that only cyber criminals who designed ransomware have. Unfortunately, victims who pay a ransom usually get scammed - cyber criminals do not send them a decryption tool and/or key even after a transaction. In most cases victims can recover their files for free only if they have a backup of data that was created before ransomware attack. It is worthwhile to mention that files remain encrypted even after removal of ransomware. However, by uninstalling ransomware victims prevent it from causing any further data loss (encryptions).

There are many more ransomware-type programs that are designed to encrypt victim's files and create ransom note in a form of text file or pop-up window too. In most cases the main differences between them are cryptographic algorithm (symmetric or asymmetric) that is used to encrypt data and price of a decryption. Here are some examples of other ransomware: Npsk, ProLock and Velar. There are not many cases where files can be decrypted without having to use tools that only developers of a particular ransomware have. In other words, files can be decrypted without their tools only if ransomware is not finished (has some bugs, flaws) and it does not happen often. Therefore, it is important to always have data backed up and keep it on unplugged storage device and/or remote server like Cloud.

How to protect yourself from ransomware infections?
Irrelevant emails that contain attachments (or web links), are sent from unknown/suspicious addresses should not be trusted. If there is a reason to think that it may be not safe to open email contents, then they should be left unopened. Furthermore, it is not safe to download, install software through third party downloaders, installers, and other channels of this kind. It is recommended to use only official websites and direct download links for that. Installed software should be updated and activated (if necessary) with tools or functions that are provided by official software developers. Tools that supposed to activate licensed programs for free are not legal and can be the reason behind installation of various malware. And finally, operating system should be regularly scanned for threats with up-to-date and reputable antivirus or anti-spyware software. Detected threats have to be eliminated as soon as possible. If your computer is already infected with Vhd, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Vhd ransomware virus infiltrating your PC).
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 Vhd 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 Vhd 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 Vhd ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
