Google returns PHP errors

Advice needed, I dont even use PHP!

[steve]

About a year ago I added a ASP based directory to my site.

Using 'site:www.******.com' Yahoo and MSN list each entry, returning www.******.com/****-directory/type.asp?iType=24 etc. along with the correct title and description

Using the site search command Google returns:-

PHP Fatal error: Unable to open d:\home\******\public_html\**** ...
PHP Fatal error: Unable to open d:\home\******\public_html\****-
directory\products\index.php in Unknown on line 0

Google spiders my ASP based forum correctly.

The server is set up for PHP but I don't use it, everything is ASP.

I'm at a loss, can anyone suggest what I should be checking?

Could you have been hijacked? It's possible that someone hijacked you with a redirect, and it is their PHP page showing up in the results.
