Name %Windir%\msn.exe


Backdoor.Ducy is a backdoor Trojan horse that uses MSN Messenger to give an attacker access to your computer.

When Backdoor.Ducy is run, it creates the file, %Windir%\Msn.exe.

Then adds the value: "control"="%Windir%\msn.exe "
to the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Also, it opens a backdoor on the infected system, allowing an attacker to connect to the system using MSN Messenger.

Manual removal:
Navigate to the key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
and delete the following value: "Control"="%Windir%\msn.exe"

Or use antivirus (also check How To Remove section)Startup Optimizer to automatically remove this troajn.
