C4H is a ransomware program that prevents users from accessing digital files on their computer and asks them to pay a ransom. To block access, C4H applies encryption to the targeted files, thus, it is considered a cryptovirus.
Ransomware threats are very common extortion tools, used to quickly raise money through blackmail for cybercriminals. These threats are often very successful in remaining undetected by the computer’s security software while applying their complex encryption to the files of the victim. Usually, they do not display clear signs of their activities and do not trigger a response from most antivirus programs.
C4H is specifically designed to target digital data and to lock it with the help of a complex encryption code that cannot be reversed without a decryption key. This infection demands money from its victims to undo what has been done to the files. The hackers that stand behind this infection typically place a .txt file on the screen which serves as a ransom note and explains how to send the money to their cryptocurrency account. In exchange for the payment, they promise to provide the victims with a corresponding decryption key that can reverse the encryption that C4H has applied.
But trusting the promises of the same people who are responsible for hacking your machine and encrypting your own data isn’t the best thing you can do. After all, C4H’s hackers do not worry about whether you can retrieve your files or not. The only thing they are after is your money, and when you send it to them, it is very likely that they disappear without sending you a decryption key or whatever file-recovery solution.
The C4H Ransomware
The C4H virus is a ransomware-based infection that scans infected computers for specific digital files and encrypts them with a complex algorithm. The ultimate goal of the C4H virus is to restrict the owners’ access to them and to demand a ransom for a file decryption key.
Users who keep really important files on their computers are the ones that are most affected by the attack of C4H. They may lose access to the encrypted information and may never be able to get it back even if they fulfill all the ransom demands or remove the ransomware from the system. This is because once the complex encryption code is applied, there is no guarantee that it can be reversed successfully. Even the decryption key that the hackers promise to send may fail to do that. Not to mention that the crooks may never send such a key to the victims.
Those who keep backup copies of their information on external drives, cloud storage or another device, however, can easily recover from the ransomware’s attack. They only have to remove the infection from the computer in order to safely connect their backup sources and copy their files back. The problem arises when there is no backup and the encrypted files are very important. In this scenario, victims are advised to consider all the available options to better deal with the ransomware. Fortunately, such options exist and, in the removal guide below, you can find a section with some of the possible file-recovery suggestions.
The C4H file decryption
The C4H file decryption is a method of file recovery, which makes the files encrypted by C4H accessible again. The C4H file decryption requires a specific decryption key that is available only in exchange for a ransom payment.
If you don’t want to pay ransom to cyber criminals, we recommend that you first investigate our guide on how to remove the virus and explore our free methods for file recovery. If nothing works, you may also want to explore other alternative methods online or even contact a specialist rather than giving your money to anonymous hackers.

Reboot in Safe Mode (use this guide if you don’t know how to do it).
WARNING! READ CAREFULLY BEFORE PROCEEDING!
Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous.

Hold the Start Key and R – copy + paste the following and click OK:
A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:
If there are suspicious IPs below “Localhost” – write to us in the comments.
Type msconfig in the search field and hit enter. A window will pop-up:
Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.
- Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.
Type Regedit in the windows search field and press Enter. Once inside, press CTRL and F together and type the virus’s Name.
Search for the ransomware in your registries and delete the entries. Be extremely careful – you can damage your system if you delete entries not related to the ransomware.
Type each of the following in the Windows Search Field:
Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
