If I delete it my parents would be mad.
Is there a way for them to find out if it's--
Wait. I had an idea. Sort of a taste of their own medicine:
First, uninstall it.
Next, go to your internet's browser's icon, right click.
Select Internet Properties>Content>Settings, Content Advisor should pop up.
Go to the Approved Sites tab, and type in the address of the Netnanny website, make it restricted, and they can't re-download it.
Hehehe, I'm evil.
