After payment, we will send our decoder and decryption code to your computer within a few hours. You just need to run it and it will ensure that all the files are automatically decrypted (unless you have renamed or changed them)! Don't worry, if the conditions are met, all your data will be restored and deleted from our server. We have no reason to cheat you after payment. < < Where can I buy and send Bitcoins?> > The easiest way to buy Bitcoins is through the LocalBitcoins website.
