WannaScream ransomware removal instructions
What is WannaScream?
WannaScream was discovered by S!Ri. This ransomware encrypts files, changes their filenames, creates a ransom note and displays another one in a pop-up window. WannaScream renames all encrypted files by adding email address (email@example.com), victim's ID and appending the ".WannaScream" extension to their filenames. For example, it changes "1.jpg" to "1.jpg.[Filemgr@tutanota.com][1E857D00].WannaScream", and so on. WannaScream creates a ransom note, a text file named "README.txt" and displays another one in a pop-up window through the created "WannaScream.hta" file.
Typically, people who have their computers infected with ransomware cannot decrypt their files without a decryption tool and/or key that can be provided only by cyber criminals (developers of a particular ransomware). In order to get instructions on how to purchase a decryption tool from WannaScream developers victims have to contact them by writing an email to firstname.lastname@example.org or email@example.com. They have to provide the appointed ID and then wait for further instructions. Also, victims are offered a free decryption of no more than 5 files that do not contain any valuable information, those files can be sent to cyber criminals by attaching them to an email. According to cyber criminals behind WannaScream, price of a decryption tool depends on how fast they will be contacted. Unfortunately, there are no tools that could decrypt files encrypted by WannaScream ransomware for free, at least not at the moment. Also, most of the times files remain encrypted even after removal of ransomware. Typically, the only way to recover files for free (without having to use tools that can be purchased from cyber criminals) is to restore them from a backup. We do not recommend to trust any cyber criminals and pay them a ransom, quite often victims who pay them get scammed (cyber criminals do not send them decryption tools and/or keys as they promised).
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
As a rule, ransomware is a type of software that is designed to encrypt data so that victims would be forced to pay a ransom and create a ransom note (and/or display a pop-up window) with instructions on how to do that. Here are examples of other ransomware: Pashka, Roll Safe and Bablo. In most cases two main variables are price of a decryption and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt data. As we mentioned in the previous paragraph, usually cyber criminals are the only ones who have tools that can decrypt files encrypted by their ransomware. It is possible to decrypt files without their tools only when ransomware contains some bugs, flaws, or is vulnerable in some other ways. Since it does not happen often, victims can recover their files only by using a backup that they created before ransomware attack. That is why we recommend to always have data backed up and keep it on some remote server or unplugged storage device.

How to protect yourself from ransomware infections?
Files attached to irrelevant emails that are received from suspicious, unknown addresses should not be opened. The same applies to website links. It is worth mentioning that cyber criminals often disguise their emails as official and important. Furthermore, all files and programs should be downloaded from official and trustworthy websites, none of the other sources that we mentioned in the previous paragraph above can be trusted/should be used for that. Also, it is important to update installed programs through implemented functions or tools that are provided by official software developers. If installed program is not free, then should be registered (activated) properly. it is not legal to use software 'cracking' tools for that and they often lead to installation of malicious software. One more way to keep a computer safe is to regularly scan it with some reputable anti-spyware or antivirus suite and make sure that it is up to date at all times. If your computer is already infected with WannaScream, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 WannaScream 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 WannaScream 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.
