First off, please wrap lines at 70 characters.

As far as "recovering" this machine, your best bet is to do a backup
of all the _data_ (NOT executables) on the mahcine, ie, html, or
whatever, then do a complete reinstall.  Otherwise you risk a
backdoor remaining in the system and wasting even more of your time
and reasources.
