Ransom Note

Q: What's wrong with my files? A: Ooops, your important files are encrypted. It means you will not be able to access them anymore until they are decrypted. If you follow our instructions, we guarantee that you can decrypt all your files quickly and safely! Let's start decrypting! Q: What do I do? A: First, you need to pay service fees for the decryption. Please send $300 worth of bitcoin to this bitcoin address: 12t9YDPgwueZ9NyMgw519p7AA8isjr6SMw Next, please find an application file named "@[email protected]". It is the decrypt software. Run and follow the instructions! (You may need to disable your antivirus for a while.) Q: How can I trust? A: Don't worry about decryption. We will decrypt your files surely because nobody will trust us if we cheat users. * If you need our assistance, send a message by clicking <Contact Us> on the decryptor window. �
