I am by far a computer wiz. With that said. I installed it on an old out dated machine. This one. It took 4 tries to install it. The first 3 times it locked up the cpu at 100%. After I finally got it to install, my Xp sp3 would not recognize that I had any virus protection. This beta version is very buggy. All I can say is the look is great. It will show you how much of the processor you are using and how much it is using on a dual vertical graph. When I finally got it to install on my computer I was able to up load and down load much faster on the internet as compaired to my NIS 2008. How well it will protect you I can't say. If the final version is as promised it will be great. For now don't install it. Way to buggy even for a beta version. jm2cents
