We received some reports from HongKong that a new MSN worm variant began spreading via MSN Messenger now. This variant can send a file "IMG024.JPG.zip" to the friends of MSN lists. In the .zip file, it contains a .com file "IMG024.JPG.com", the size is 37,888 bytes, Kaspersky detects it as Backdoor.Win32.Rbot.csm.

This variant sends out the following message according to the language of Operating System.

hey, what should i do, if i havbe opened it?
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"ehSched"="%Windows%\system\ehSched.exe"

delete this registry item first, and then delete these files after restarting:

%windir%\system\ehSched.exe
%windir%\system\IMG024.JPG.zip
