“Locker“-named viruses have become a new wave. The virtual community has already seen similar threats: Wicked Locker HT, Wildfire Locker, etc. They all seem to be entitled in the fashion of original CryptoLocker virus – which still leaves a menacing awe for many hacker-wannabees. Obviously, some crooks clearly mock their victims and create supposedly amusing ransomware veneers and ransom notes. However, dealing with a file-encrypting malware is surely an unpleasant experience. The new virus – Happy Locker ransomware – is supposed to be another alternative of Hidden Tear 2.0 virus. It seems that its authors decided to revive the ransomware and generated its several new versions.

The current virus has gained such notoriously ordinary title as it appends .happy extension to all affected files. Unfortunately, the virus targets a broad range of files so the majority of your image, audio, video and .doc files might be already encrypted and bearing the mentioned extension. After the process is finished, the virus opens READDDDDDD.txt containing scarce instructions how to decrypt the files. certainly, they demand money in exchange for the decryption software. However, we would like to remind you once again that hackers have an awful peculiarity not to keep their word. In short, you may waste your money and the last drop of patience.
