This freeware program is a simple portlistener that listens on a specified port, for example the netbus trojan or sub 7 trojan port. It will log any attempt trying to connect on that port on your PC and will make a beep or sound to notify you. It gives the possible hacker's IP and host so you can find out his ISP and mail them about the hack attempt. Make sure you read the included readme.txt first. Download Portlistener 1.0
