say I'm trying to crack my house wifi wep key ( i know the key i just want to test it ) and i do it from my room with my laptop and im not connected to the internet. Next room is my brother who is using the home desktop computer with like norton or kaspersky internet security installed in it. when i am running gerix wi fi craker, will kapserskey or norton alert my brother that someone is intruding on the network or anything like that? will the security then maybe track me back to my laptop?

what if i run the cracker while the main desktop computer is turned off? im just wonder in about these and any help would be appreciated.
