My computer and hard drive are attacked by the ransomware virus and all the files inside devices changed to .bopador extension. Files are very important. Can I recover my files ?
"Files are very important. "
Surely there is a full backup of this important data?
Ransomware is particularly nasty, because unless there is a published decryption routine, you are 100% out of luck.
This particular variant seems to use a private key...each person gets a different one.
Meaning there is no generic 'undo'.
