Brief Description 

    

Ransom.AB is a Trojan designed to blackmail users, as it causes the computer to be blocked and asks $12 for some software to unblock the system.

When it is run, it displays on screen an email message in Russian (in case users have the OS in Russian or the corresponding language packet) and prevents users from working with their computer.

This is why it is a malware mainly designed too affected Russian users.

Ransom.AB does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer.

  • If users do not have the OS in Russian or the corresponding language packet installed, they will see the message in the following way:
