Infected with THT Ransomware? Need to decrypt your files?

What is THT Ransomware

THT Ransomware is a cryptographic virus, created by TimisoaraHackerTeam, which became most active at the end of June this year. Like many similar extortionists, it encrypts key and most valuable user files, such as documents, photos, video files and much more. After encryption, the user cannot open these files, because the virus changes their extensions. Sometimes, the virus targets server systems. It is impossible to decrypt files independently because the virus deletes all system restore points and backup copies of files. The main task of THT Ransomware’s developers is to make you pay to decrypt your files. That’s why the developers have created a special text file Readme unlock.txt, which opens with each attempt to open the file:
