Hi Guys! I have a problem or question about port 80 and it's security. Here is a my question, I hope somebody can help me with this. I have Windows Vista and I just installed Appserv 2.4.9 (http://www.appservnetwork.com/) into my computer so I can create and test my PHP sites... I have a wireless router which is: linksys BEFW11 version 4. Well I went to my router configuration and open port 80 in order for people to be able to see my "testing sites". Somebody told me that he access my local server and put something there, I don't know what it's, he made reference to my php info, he send me a screenshot of my php info and he made a reference to this: Code: _SERVER["PATHEXT"] .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC Can somebody please tell me what this line means and can if it's insecure? Can sombody access my PC and all my personal files because of this? How can I prevent this and what is the first step to figure out what he did? I'm really concern about this guys... I need some help and. For now I'm scanning my PC with Trend-Micro PC Internet Secutiry 2007 for some spyware or keylogger, I don't know, I don't know how to see if he insert a keylogger into my system and how to remove it.
