Im relatively new to this kinda stuff, so cut me some slack Our schools using a program called Netsupport School to spy on what anyone is doing at any time, with full rights to lock your keyboard and mouse while they check what youre doing. I dont feel this is fair at all, and we should be able to block this. After doing some research, I found that the program uses ports 5405 and 5421, both udp and tcp. Is there a program I can run on the computer that will block any incoming attempts on these ports, or even better, disable the program? Theyve tried to disable people getting into the C drive and whatnot but you can get there with certain programs. Any help would be great.
