lsof.

Specifically, look for the process id of the process that  you don't want,
and run something like "lsof -p 317".  One of the very first things listed
will be the executable that it ran from, followed by lots of libraries (and
other dynamically loaded objects, aka ".so files").

Another thing to try.  Get the process ID again.  Usually there's one
httpd/apache process running as root and the rest as "apache" or "http" or
"www-data" -- for the lsof thing it didn't matter which you got, for this
you really need the one that's running as root.
"strace -p 317"
Then in another console, "kill -HUP 317"

This will tell the apache process to reload its configuration, which will
naturally involve loading all the configuration files.

And, of course, "ps auxfw" is handy for this kind of thing.

You didn't mention which distro you're using, but I would definitely
recommend using the information you gather from the above to find out which
package has the files causing you the problems, and tell the package
management system to remove those packages...  Try working with your package
management system before ripping things out manually, or you risk leaving
roots that will sprout again and you'll never get the kudzu out of your
engine compartment.
