Don't be mad at him. He wasn't expecting to find what he did; he was a fifteen-year-old looking for clues, is all. And it's he probably figured the password out on his own - it is his own password, so it's likely it was something he'd recognize even as a teenager. He was upset about it, and since he was the only person I was talking to during the virus who wasn't exceedingly creepy or a toddler, it made sense to help him out. You can't blame him for wanting to know - you said so yourself, you'd do the same thing.
