1) seems the more probable cause; it is often easy to add a CC address from the address list (for example) if you are not attending to what you are doing.
2. I don't see why a virus would WANT to do something like that; as you wrote, the motive for doing so seems unclear. If this has happened only once, and not on a regular and consistent basis,it would not be a virus. Just for ease of mind, though, you might want to test this by having her send several messages to your E-mail address to see if there is a unwanted CC and watch what she does when composing the test messages.
Whereof one cannot speak, thereof one should be silent.
