Thanks genius_at_work! I've created a small script which prevents links from being displayed and it work great! She wasn't able to see any links and didn't even notice she was not able to. Thanks a lot, this idea was very clever.
//Edit
Our computer searches for keyloggers when it start-up and there's no way to set an exception to one. My idea was that a Scanner can't scan scripts, so only me and my parents would know of it.
