"Good for when you are cleaning an infected PC"
Lets you work outside of the system to update or reinstall certain programs without necessarily being blocked or bogged down by the virus you are trying to defeat. Leaves no registry trace nor temp mess when you are finished on your system that I can tell.
A little slow, but still unbeatable surfing security.
Not as succeptable to rootkits. Portable.
