I thought the mods of this forum may like it for doing virtual pcs for the training, since you can do scans very quickly, unlike a true virtual pc.
THe program is also nice for testing out software or traveling to the dangerous parts of the internet, or wanting to play a game with malware in it(don't recomend bad surfing habits by the way).
When the pc is rebooted, everything is restored to the perfect shape it was in. Pretty sweet eh?
