Interesting development.

Your system has obviously been compromised. Disconnect the NIC's physical
connection to the switches for this server from the network and isolate the
problem - systematically approach the problem with logical steps.

Setup a temporary packet filter for FTP on your external address/WAN side NIC -
this will block all incoming packets for FTP or alternately only allow the ports
you know that are needed for appropriate public access to your server.

Try looking at symbolic links and partitions mounted to a directory and non
standard permissions on such.

There was possibly a registry change which may prevent you from
changing/deleting
the suspected resources.

Run appropriate scanners for viruses/trojans/worms/embedded scripts.
