My pictures were encrypted with ljaz and cdaz viruses, I can't decipher them
The .ljaz and .cdaz extensions are associated with the Djvu Ransomware family. This ransomware encrypts files and appends these extensions to them, demanding a ransom for decryption. Unfortunately, there is no guaranteed free decryption tool for files encrypted by this ransomware.
Upload the ransom note and the encrypted files to https://www.bitdefender.com/en-us/blog/labs/bitdefender-ransomware-recognition-tool and https://id-ransomware.malwarehunterteam.com/ . It will identify the type of ransomware and inform you whether any decryption tool is available. If there is no decryptor available, you will need to create a backup of your encrypted files. If a decryptor becomes available in the future, you can use it to decrypt your files.
