Can't prevent php files from being searched

Is this possible

[Jack_mcs]

I ran my site through the simpulator at [webconfs.com...] and it shows that many of my .php files are being searched even though I have a disallow for them. For example, it shows account.php and in my robots.txt file I have

User-agent: *
Disallow: account.php

I have also tried it as
Disallow: /account.php

and have even tried deleting this entry altogether.

I have also put <meta name="robots" content="noindex"> in account.php.

With all of the above, the result is the same. Is there a way to prevent these files from being searched?
