I like what PowerShadow does to me, a reboot will get rid of anything I made in the shadow mode, just like DeepFreeze and free too.

I'm just forced to use an anti-malware because my bro is angry with new security huhas, he just wants convenience.
I played with Sandbox for a couple of hours, and what I like about it is for the more simpler, lighter "virtualization" it provides plus I have the freedom to choose a program to be in a sandbox and the other outside. I'm just a sort of double clicker and rarely bothers to right click except for "Refresh" and "Properties".
