W32/Kingdom-A is a worm which attempts to spread over KaZaA Peer-to-Peer (P2P) file sharing networks.
Upon execution, the worm drops itself to C:\Windows\Sys32 as kingdom-hearts.exe and modifies the following registry entries
HKCU\Software\KaZaa\LocalContent\DisableSharing
HKCU\Software\KaZaa\LocalContent\Energy
The above changes enable P2P file sharing under KaZaA and make C:\Windows\Sys32 a shareable folder.
