How do I disable Net Nanny from working on my computer?

[lemon pledge]

My dad installed Net Nanny on my computer, and I feel like it is a complete violation of my privacy because he can see every website that I visit now (please keep opinions on freedom of privacy to yourself).

I was wondering if there is any way that I can remove it from my computer permanently, or if there was some kind of loophole where I can visit any website I want without it showing up on the history on his computer.

I have a Windows 7 laptop, and the version of Net Nanny is 6.5

One more thing is that people are making the assumption that I'm watching pornography which is not true. My dad won't allow me to have a Facebook account, and that's the only reason I would like this software disabled.

Get a USB drive. It needs to be blank (or have nothing important on it anyway).
Get this: http://unetbootin.sourceforge.net/
Make a Linux live USB, and boot using that. Now anything you dad did to Windows in completely irrelevant.
