Ransom Note
::: Hey ::: Small FAQ: .1. Q: What's going on? A: Your files have been encrypted. The file structure was not affected, we did our best to prevent this from happening. .2. Q: How to recover files? A: If you want to decrypt your files, you will need to pay us. .3. Q: What about guarantees? A: It's just business. We are absolutely not interested in you and your transactions, except for profit. If we do not fulfill our work and obligations, no one will cooperate with us. It's not in our interest. To check the possibility of returning files, you can send us any 2 files with SIMPLE extensions (jpg, xls, doc, etc... not databases!) and small sizes (max 1 mb), we will decrypt them and send them back to you. This is our guarantee. .4. Q: How to contact you? A: You can write to us at our mailboxes: [email protected] .5. Q: How will the decryption process take place after payment? A: After payment, we will send you our scanner-decoder program and detailed instructions for use. With this program you will be able to decrypt all your encrypted files. .6. Q: If I don't want to pay bad people like you? A: If you do not cooperate with our service - it does not matter to us. But you will lose your time and data because only we have the private key. In practice, time is much more valuable than money. :::BEWARE::: DO NOT try to modify encrypted files yourself! If you try to use third party software to recover your data or antivirus solutions - back up all encrypted files! Any changes to the encrypted files may result in damage to the private key and, as a result, the loss of all data. Note: ::::::IF WE HAVE NOT RESPONSE YOU BY MAIL WITHIN 24 HOURS:::::: Spare contact for communication: If we have not answered your email within 24 hours, you can contact us via the free messenger qTox Download from the link https://tox.chat/download.html Next go qTox 64-bit after downloading the program, install it and go through a short registration.
