Am currently running Xammp-Apache so that I can work with PHP files. I also like to be connected to the internet at the same time so I can download files / browse when needed etc. I ran Steve Gibson's port scan with and without Xammp-Apache on, and noticed when it is on, port 443 is not stealthed by ZoneAlarm (free version; 5.5). I could not make out from his website whether or not this mattered.
I have set a line which says Listen 80 to Listen 127.0.0.1:80 in httpd.conf so that Apache only listens locally. Perhaps there is another line to protect 443?
Any help appreciated!
