Technical DetailsThe worm copies itself as the following hidden files:
C:\%SystemDIR%\WINTSK32.EXE
C:\%SystemDIR%\EXELDR32.EXE

It makes the autostart registry entries:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run MicrosoftServiceManager %SystemDIR%\WINTSK32.EXE
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices MicrosoftServiceManager %SystemDIR%\WINTSK32.EXE

To be activated every time an .exe file is opened, the worm modifies the registry:
HKEY_LOCAL_MACHINE\Software\Classes\exefile\shell\open\command "%SystemDIR%\exeldr32.exe"%1 %*

It copies itself in C:\%Windir%\%Systemdir% as:
