How to remove HappyLocker ransomware and decrypt .happy files

What is HappyLocker?

When you see the black screen with the message that your files was encrypted with “happy”, well, it means your system infected with Happy Locker. HappyLocker is a ransomware-type virus that is designed to encrypt the victim’s data to further blackmail users. Symmetric encryption algorithm- AES-256 is used for this procedure that significantly complicates the task of decryption. The process itself does not take much time so the user may not even notice anything suspicious. As a result, each affected file will be appended with .happy extension, for example, myfamily.jpg is changed to myfamily.jpg.happy. At the end of encryption, HappyLocker Ransomware leaves 2 files ((“READDDDDDD.txt”, “READ.bmp”) with instruction on how to restore your files.
The spread of the virus is done through spam messages, cyber-criminals just insert infection into the attachment under the guise of a regular .doc or jpeg file. Latest research also shows that they started using P2P networks and fake downloads containing malicious files for spreading.
