I set up MSN Messenger for a friend recently and noticed today that she appeared to be online. However, she doesn't have a computer and I knew she was at home. She had been to a couple of Internet cafes to use MSN Messenger in the last couple of weeks and has probably not signed out of a particular machine.
Is there a way I can secure her account as it seems someone else is using it? I have changed her Hotmail e-mail password as an emergency measure but i'm not sure if it's enough.
