I agree with the firefox suggestion. IE and M$ is the IT cancer.

Personally, I use FreeBSD . If you want to see it in action, click here . No spywares, no adwares and yes, I have Limewire too.

It's not for the inexperienced Windows user though, but you'll never know if you don't try. I keep a seperate XP partition just for games, the rest I do in FreeBSD.
