The appearance of Cryptobyte Ransomware may mean that all your files have been lost since the application is a vicious file-encrypting threat. The malicious program’s creators may try to convince you that the best option is to pay the amount of money they ask you to, but we have to warn you that such deal is extremely dangerous. There are no guarantees they will deliver you a working decryption tool, so there is a chance you could lose the transferred sum in vain. Instead of taking such a huge risk we advise you to look for other recovery options, e.g. copies from flash drives or other storages, recovery tools, and so on. Just keep it in mind, there is no need to leave Cryptobyte Ransomware on the system, and for safety precautions, it would be best to eliminate it as fast as possible. For detailed instructions on how to erase it, check the steps provided below this text.

It looks like the malicious program might be distributed via infected attachments sent through Spam emails. If you recall receiving any suspicious letter before you found out the computer was infected with Cryptobyte Ransomware, the attachment in it was most likely the malware’s launcher. As you realize it, you could have avoided the threat and data loss by simply scanning the suspicious file with a reliable antimalware tool instead of carelessly opening it right away. For users who do not have such software on their computers, we would advise considering acquiring legitimate security tools, especially if there is valuable information or data on the device. In such case, it is also advisable to stay away from malicious web pages, unreliable software installers, questionable file-sharing sites, and any other doubtful content you may come across while surfing the Internet.

From what we have learned it would seem Cryptobyte Ransomware is targeting an enormous amount of different file types. Thus, chances it would leave at least some of your personal files unaffected are close to zero. As soon as the threat infects the system, it should lock all your pictures, photos, documents, videos, archives, and any other data except the files belonging to the computer’s operating system. The unaffected data should have its original title and extension, while the encrypted files might by marked by .crptxxx or a similar additional extension. Afterward, the malicious program is supposed to drop a ransom note stating the user should contact the cyber criminals if he wants to purchase the decryption tool. This note could appear on the desktop or directories containing encrypted files.

Naturally, we advise you not to risk your money and pay no attention to the displayed demands. Instead, we would recommend cleaning up the system by removing Cryptobyte Ransomware with the deletion instructions located below the article or a reliable antimalware tool of your choice. Once you are sure the computer is secure and the infection is gone, you could try special recovery tools or restore encrypted files by switching them with copies from external hard drives, cloud storage, and so on.
