This program would be a great example of "security by obscurity"?
Might be a good way to trick the kids... but they'd eventually get around it if they were determined.
There are too many ways to kill it, detect it and basically get around it.
like i said, a dad asked for a tool like this, since a friend of him has such a tool and he didn't know what it was called.
so i wrote it. he only wanted to block iexplore.exe but i thought lets make it simple and let it be any program .

I opened several (5) command shells. Within each command shell I started
"Exekiller someexe.exe".

Slowly, but steadily, the Exekiller filled up the memory, even when I killed
all the cmd.exe-processes I previously opened. Does anyone observe the same?

I checked the code but could not see anything "obvious".
i see what you mean. and i think i know how it happens:

since exekiller is started as a child process from the cmd.exe and hides the window, and then get killed, the window from cmd.exe still stays hidden and cmd.exe stays open.

so here's how i solved it:

if added
Code:
ShowWindow(stealth,1);
before every possible exit from the program, this way when you press <CTRL>+<SHIFT>+<BACKSPACE> you get your command back again and can kill it with the exit command.

i will upload the new zip file right away, so if you want you can download it again in about 5 minutes from now

thanks for the comment sec_ware, i didn't noticed it myself before...
well, the first bug is found and solved
