This "systemwork" actually screw up my computer performance. I installed it on two different computer, and yield the same result: 1. If installing all the components of this software, the startup time for the computer increase by 5 times. 2. I uninstalled the Go Back and Ghost, it still at lease double the startup time. Not only the start up time is longer, this software substantially lower the performance of my two computers. It now takes longer to load any applications. Before I install this, I was using the 2004 version, and that was much better than this (at least did not slow down my system by that much), I feel like everytime norton introduces a newer version, it slows down system more. I really would not recommend people buying this.
