Ransom Note

What Happened to My Computer? Your important files are encrypted. Many of your documents, photos, videos, databases and other files are no longer accessible because they have been encrypted. Maybe you are busy looking for a way to recover your files, but do not waste your time. Nobody can recover your files without our decryption service. Can I Recover My Files? Sure. We guarantee that you can recover all your files safely and easily. But you have not so enough time. You can decrypt some of your files for free. But if you want to decrypt all your files, you need to pay. You only have 3 days to submit the payment. After that the price will be doubled. Also, if you don't pay in 7 days, you won't be able to recover your files forever. How Do I Pay? Payment is accepted in Bitcoin only. Please check the current price of Bitcoin and buy some bitcoins. And send the correct amount to the address in this. Once the payment is checked, you can start decrypting your files immediately. Contact If you need our assistance, send a message by Telegram. We strongly recommend you to not remove this software, and disable your anti-virus for a while, until you pay and the payment gets processed. If your anti-virus gets updated and removes this software automatically, it will not be able to recover your files even if you pay!
