It doesn't mess with your computer. It does install a couple of spyware programs called "Save Now" and "Weathercast" which does not do any harm. I just disable it and if you have firewall, it won't go through if you don't allow it to go through. Other than that, I love it. I download a lot of stuff including movies, music, games, software of any kind.
*Fact: Microsoft Window's Blue Screen of Death vs Computerforums.org's White Screen of Death. Which is worse?
