I only looked briefly at that webpage and already saw something that ain’t right.

Test simulates virus, spyware and hacking attacks
Testing to see what happens with hacking attacks should be done from the outside of a system/network, not from within the inside.

Furthermore, if you need help with the util, you need to contact their webmaster ;D

There is also no eula, faq or any more detailed information on the website.

Looking at this, I would say not even worth to download.
