  • If it encrypts your files, you cant access that file. You are left with files but cant open any.
  • After encrypting all files it will notify you about its presence. It will show you a message to pay a certain amount of money in the form of bitcoins.Bitcoins are a cyber-currency that are very difficult to be traced to the receiver.
