If you are not interested in researching the malware on the machine,
nuke and reinstall. Sure, it may just be an innocuous misconfiguration,
but reinstalling tends to be at least as fast and give better results,
too. In any case, take it off the net, or the rest of your LAN may be
zombified soon. Like, yesterday.
