Shelly is having trouble typing in her web browser. When she types, all different letters show up! Leo says that it's possible that she changed the keyboard mapping and that's what could be causing it.
The chatroom says that a malicious toolbar could be causing the issue. Leo recommends disabling all the toolbars she has, and restarting her system. Leo also suggests plugging in a different keyboard. If that doesn't change it, then it's definitely software. It's likely a virus that's embedded in the toolbar.
She could also try logging out of that user account and logging into another one. If she restarts Firefox in safe mode, that'll show her if there's something going on as well.
