Is this normal? Can any ports be "dangerous"?
I have 9 tcp's in a listening state, 4 in a close_wait state, and 4 in an established state.
Some of them route to odd procceses using PID such as default tab.exe. A lot of them are from IObit in states: close_wait and established.
Something I am worried about is some of the PID aren't showing up in task manager, not sure if that is a product of it being my local address with like :135, 445, 554...etc... what does those numbers mean at the end?
Example would be : (local adress) 0.0.0.0:135 to foreign address 0.0.0.0 State is listening, PID is 940 but I can't find the PID so I'm not sure what proccess is causing it and that seems odd.
Ok, so now I actually know what TCP is but I'm still wondering why the PID is not showing up on task manager for some of the connections?
