Yeah, Port 80 is open and I want to close it. But I can't find which software is using it. I have already typed netstat -aon in cmd but I can't find which software is using port 80. There is some software using it with PID 0 but I'm not sure which software is using it. I have even tried to reset my router to factory settings, but it still didn't work.
When you see a remote port in TIME_WAIT it means that YOU recently were connected to a remote computer and the connection has been closed. The connection is briefly kept alive in case any stray packets still come in from the remote computer.
