This seems to be a newer variant on ZA; ran into one of these yesterday actually.

Haven't tied it on x86 yet, but on x64 its added a service that re-infects the Session Manager\Subsystems\Windows key on boot.

Yeah, this version has an extra layer of protection. Many NetSvcs are being inserted, and the junctions are recreated on every reboot.
