Can't you find the necessary files?
Is the content of your files not readable?
It is normal because the files' names and the data in your files have been encrypted by "Cerber Ransomware".
It means your files are NOT damaged! Your files are modified only. This modification is reversible.
From now it is not possible to use your files until they will be decrypted.
The only way to decrypt your files safely is to buy the special decryption software "Cerber Decryptor".
Any attempts to restore your files with the third-party software will be fatal for your files
