In order to run automatically when Windows starts up the Trojan copies
itself to the file mmsnmessengerupdate.exe in the Windows system folder and
adds the following registry entry to ensure it is started on computer logon:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
svshostdriver = msnmessengerupdate.exe
