When first run W32/Forbot-GI copies itself to <Windows system folder>\drivers\ntndis.exe and creates the file <Windows system folder>\drivers\ntndis.sys.
The following registry entry is changed to run ntndis.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Shell
Explorer.exe <Windows system folder>\drivers\ntndis.exe
(the default value for this registry entry is "Explorer.exe" which causes the
Microsoft file <Windows folder>\Explorer.exe to be run on startup).
The file ntndis.sys is a rootkit detected by Sophos's anti-virus products as Troj/RKProc-F. Ntndis.sys is registered as a new system driver service named "ntndis", with a display name of "ntndis" and a startup type of automatic, so that it is started automatically during system startup. Registry entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\ntndis\
