I'm trying to explain to my 14 year old daughter why she shouldn't run e-mail attachments, but like most teenagers, she thinks it couldn't possibly happen to her. I would like to give her a harmless demonstration.

I know I have seen a program that merges two executables, I assume for the purpose of creating trojans. I'm not having any luck finding it. Could someone either give me the name or a link.

Much apprectiated.
