Charck ransomware removal instructions
What is Charck?
Charck is a malicious program that cyber criminals use to encrypt data and to blackmail their victims (to make ransom demands). Programs of this type are categorized as ransomware. Charck is a part of Djvu ransomware-type programs. It was discovered by Michael Gillespie. When a computer is infected by it, Charck adds the ".charck" extension to every encrypte file. For example: if a file before encryption was named "1.jpg", then after encryption it gets renamed to "1.jpg.charck" and so on. It also creates a ransom note in a text file called "_readme.txt". Charck's victims should be able to find it in every folder that contains encrypted data.
The "_readme.txt" file is created to inform people about the price of the decryption tool/key, how to pay for it and how to get it. It tells that all files were encrypted but they are not lost and can be restored. To decrypt data it is required to purchase a decryption tool and unique key that cost $980. However, Charck's developers offer a 50% discount for people who contact them in the first 72 hours after encryption - a decryption will cost $490 then. To get details on how to make a payment it is required to contact them via firstname.lastname@example.org or email@example.com email address. Email should contain a personal ID that is appointed to every victim individually. Before paying, Charck's victims can send one file to them and they will decrypt it for free. Cyber criminals use this offer as a way to prove that they have a working decryption tool and key. Typically, cyber criminals (who developer ransomware-type programs) use cryptography algorithms (symmetric or asymmetric) that generate unique decryption keys and they store them on remote servers that can be accessed only by them. Simply said, people who have their computers infected with Charck cannot decrypt data without using a particular decryption tool/key. The problem is that its developers are the only ones who have it. It is very common for ransomware developers to use "uncrackable" cryptography algorithms that are impossible to decrypt without using a right tool. What is worse, most cyber criminals cannot be trusted: they do not send promised decryption tools to their victims even if their ransom demands are met. People who trust them/send them money (usually, cryptocurrency) get scammed. The only (and free) way to retrieve files in such cases is to use a data backup that was created before encryption and to restore them from there. There is no free tool at the moment that might be capable of a successful decryption.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Most ransomware-type programs operate very similarly: they encrypt data and display ransom demanding messages/generate ransom notes. Main differences usually are price of a decryption tool/key and cryptography algorithm used to encrypt data. Another thing that most of these programs have in common is that their encryptions are impossible to decrypt without using tools that only their developers have. A decryption without particular ransomware's developers usually becomes possible only if a program is not fully developed/has some bugs, flaws. To avoid data loss caused by ransomware we recommend to create data backups regularly and to store them on remote servers or unplugged storage devices. Here are few examples of other similar programs: Kroput, GILETTE and a800.

How to protect yourself from ransomware infections?
Carefully analyze emails that contain various attachments or website links. If an attachment or link is presented in email that is received from unknown, suspicious address (and the email is irrelevant), then we recommend not to open its contents. At least not without being sure that it is safe. Download software using official, trustworthy sources/websites and direct links. Avoid using third party downloaders, Peer-to-Peer networks (torrent clients, eMule and other similar software), questionable, unofficial websites (and other similar sources) for that. Update installed software and operating system using tools or implemented functions that are provided by official developers only. Third party updaters should not be used/they should not be trusted. Same applies to various tools that are designed to activate paid software for free: these tools not only cause computer infections but are illegal as well. And finally, one of the best ways to keep a computer safe from various infections is to have a reputable anti-virus/anti-spyware suite installed and to keep it enabled at all times. These tools usually are capable to detecting and stopping/eliminating viruses from doing any damage before it is too late. If your computer is already infected with Charck, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

As with most of ransomware from Djvu family, Charck also displays a fake Windows update pop-up during the encryption:
IMPORTANT NOTE! - Ransomware-type infections from Djvu malware family are designed to 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 carried out with the intention of making users unable to access malware security websites and seek 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).

Log in to the account infected with the Charck virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
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 Charck 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 Charck 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 Charck 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 Charck 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.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
