→C:\Users\Administrator\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\99DB.tmp

Malware researchers believe that the malware may also create registry entries with values set to run the executable 99DB.tmp and other malicious files spread by this ransomware trojan on system startup. This may happen in the following Windows Registry entry:

→“Ме:
Hello,

Please, send me a decryptor to unlock my files.
The hijacker:
Hi
If you wish to get all your files back, you need to pay 3 bitcoins.
Go to localbitcoins dot com, it’s probably the easiest way, open an account,
buy bitcoins and then ask me for the address to send the bitcoins to.
Me:
Hi,
My friend, I am from Bulgaria. 3 bitcoins are my salary for two months.
If you agree I can pay 0.1.
The hijacker:
2 btc “
