Block PHP probes using Comodo firewall

I apologize if this subject has been addressed before.

I run the Windows XP Personal Web Server out of my home. I know, antiquated, inadequate, but, it works for me.

I am wondering if there is a way to use the Comodo Firewall Network Security Policy to block non local network IP addresses which are probing for PHP components on my computer. I do not run any PHP components and I suspect any IP address looking for PHP is up to no good.

Right now, I search the Windows XP W3SVC1 log file on a daily basis for IP addresses trying to access PHP components and block the IP address in Comodo’s Network Security Policy Global Rules. As you can imagine, it is very tedious and time consuming. I’m looking for a way to define a single rule that would block all PHP probes.

If you have any suggestions or I need to post in a different forum, I would appreciate any information.
