Anyone know of a website blocking program?

[AlexLefty]

I try to control myself, but sometimes I just can't. I need a program to temporarily disable access to certain websites, especially when I'm studying.

I know of this one: SelfControl 1.4

But it's only for mac.

Anyone know of any other, virus free website blocking programs?

if you have mozilla, leachblock is good for this.
