Localhost file listing problem

[__50_Scent]

I have installed Apache 2 and PHP5b3. I checked to see what localhost would show me and it gives a file listing of all audio files and .cab files on my computer.

Could it be something to do with WinMX or Kazaa?

How do I get it back to 'normal'

Any help would be appreciated,
Thanks.

I know when Kazaa is open I had that problem, but I closed it everything was fine.
