I guess this email is Virus or Trojan. Because yesterday K.Sukawat & Captain Sompob (RSM) has double click to open this attached file from this email, after that his Windows has error and stopped working immediately. We needed recovery OS for him only.
As I asked all events has happened with them. They not sure this sender will relate with his work or not. But this message was written look like strange. And now, they had deleted this email out of his mailbox already. So, we need to beware and monitoring this problem continuous.
