The Trojan registers itself in the system registry, ensuring that it will be launched each time Windows is rebooted on the victim machine:
[HKLM\Software\Microsoft\Windows\CurrentVersion\Run] "Start"="<path to original executable file>c:\Update.bat"
The Trojan then causes the following message to be displayed:
This type of behaviour covers malicious programs that delete, block, modify, or copy data, disrupt computer or network performance, but which cannot be classified under any of the behaviours identified above.
This classification also covers “multipurpose” Trojan programs, i.e. those that are capable of conducting several actions at once and which demonstrate several Trojan behaviours in a single program. This means they cannot be indisputably classified as having any single behaviour.
