icslap abuse?

Hello,

I’ve just accidentally check my TCPView and noticed something disturbing. As You can see in the log my communicator (wtw.exe - soft for interchanging messages) is connected to my friend’s (networking expert) PC to port icslap. We are in the same LAN net (we share a flat), but I don’t talk with him using this commuicator.

Process PID Protocol Local Address Local Port Remote Address Remote Port State
wtw.exe 1992 TCP myPC 9559 myFriendsPC icslap FIN_WAIT2
wtw.exe 1992 TCP myPC 9562 myFriendsPC icslap FIN_WAIT2

Is it possible my massages are redirected to my friend’s PC?
Thanks in advance for help
