How to remove CH ransomware

Tips for CH ransomware removal

CH ransomware is a cryptovirus that operates by encrypting stored files and demanding ransom payment for the decryption. As the CH encrypts, the filenames of the encrypted files will be appended with .CH extension. For example, a file named 1.jpg becomes 1.jpg.Ch.

Rightly after that, the CH ransomware creates a .txt file that informs the users about what has happened on their device. It states that the ransomware makes the data stored including images, audios, videos, databases and presentations encoded with a unique key/code whose decryption key are stored on some remote servers belongs to the crooks behind it. They are asked to establish contact to them in order to get the tool. To gain the users’ trust, the crooks may offer free decryption services of some files. Nevertheless, you should never trust these people. They will never provide you the decryption tool even if all their demands are met. Once the payment is done, they disappear leaving you without your files. Therefore, you must use some data recovery alternatives.

We recommend you perform CH ransomware removal first before doing the data recovery. This makes you ensures that there will be no influence of the threat during the data recovery process. The malware removal is necessary to be done to prevent further files encryption and also to avoid more severe risks that the CH ransomware can create:

• It runs in stages – the very initial stage is to perform malicious modifications to the crucial system settings to gain system performances and make the executable run and perform the scan for the installed files for the encryption. Such operation can have the huge impact on the system general performances
• To complete the encryption process, the crooks require remote access to the device to gain access to the stored data related to the users that they use in designing unique ID number associated number associated to them
• The ransomware can have additional module to perform various other malicious malware injection. Thus, through the infection, there will always be a risk of dangerous banking Trojan, cryptocurrency miners or some keyloggers intrusion to the device

Therefore, you should immediately remove CH ransomware from the device. Follow manual malware removal guide provided below the post or use reputable antivirus tool to remove it from the device.

How did ransomware infect my computer?

Ransomware viruses are most often distributed via using spam campaigns, Trojans, dubious software download channels, fake software updates and unofficial software activation tools. Cyber criminals send various emails that contain infectious files or links within as attachments, if opened-the attached/downloaded files infect computers with malware. Trojans are malicious programs that cause additional installation of malware. Untrustworthy downloading channels including third party downloaders, free file hosting websites, Peer-to-Peer (P2P) networks and so on spread malware by presenting it as legit software. Fake software updaters infect systems by exploiting bugs, flaws of already installed outdated software. Cracking tools infect the devices by supposedly providing activation for paid software.

How to protect yourself from ransomware infections?

You should use official websites and direct download links for any software download and avoid all aforementioned untrustworthy downloading channels. Also, you should rely only on official software developers’ tools/functions for any software updating and activation. Further, do not open irrelevant attachments or the emails having unknown senders’ addresses. For betterment, employ some antivirus tool that prevents any malicious executables from being launched. Such tools check for updates required for the installed software and operating system time to time and also remove any issues/errors and malware before its spread and hence provide adequate protection to the device.
