243480 Personal Keylogger

I need a undetechtable Keylogger made for personal use to send to my son away at college. I need to be able to attach this keylogger to a Picture or something and the picture not be a .exe it has to remain a .gif or .jpeg I really just need it to not show up on Anti Virus programs. The log reports can be sent via Email or FTP. Like I said this will be used to send to my son no one else. Im just suspicious about something... Im not looking to spend a fortune but I will pay the right price depending on how undetectable this is.
