Thank FLOOD very much!
With the first link https://id-ransomware.malwarehunterteam.com/index.php?lang=en, I could have solved my big problem. Yesterday, I already referred to id-ransomware.malwarehunterteam.com, www.bleepingcomputer.com but could not solve it, because id-ransomware.malwarehunterteam.com, www.bleepingcomputer.com were not updated .besub. Today, it is very lucky, with your instructions, I retried it and saved the data with the new version of STOPDecrypter v2.1.0.15 that id-ransomware.malwarehunterteam.com, www.bleepingcomputer.com were updated .besub.

Thank you very much again, looking forward to receiving enthusiastic help from you.


Here the text file I have just found that ransomware left in my laptop.

Best regards!

Hello Lelong,
Thank you so much for letting us know. We are delighted the issue is resolved.
Just a friendly caution for the furture. I don't think we discussed "how" the infection happened, but, as you know from bitter experience, this type of infection is not welcome for you. Do everything you can to stay safe and protected from the bad guys!

Best regards!
