I think something is seriously wrong on my computer, but i dont know what it is. Recently i started to see my firewall was giving me warnings about that i was connectiong to unprotected networks and it asked me to protect it, so i clicked yes and now in the protected networks list theres a new network named DTN network (Direct internet connection). Now in the firewall i have been starting to see incoming connections of netbios-ns on port 137 from different ip adresses and the firewall is accepting them. And other suspicios stuff such as bootps (67) and llmnr (5355) and outcoming connections from port 64368 to ip adresses i never hear of. Do i have a botnet or other spyware on my pc? Please help!
