Safeshield

Creates a virtualization layer to prevent changes to the OS from becoming permanent.

From website: Imagine being able to page through web sites without worrying about being attacked by virus, malwares... You dont need to set up Firewall, Blacklist, or carefully watch where you are going. Turn on SafeShield to create a virtual world (a copy of your Windows) and you are safe. Whenever you are ready to get out the virtual world, restart your computer and you are going back to how everything was before as if nothing has ever happened on your computer. In addition, SafeShield works well with all popular firewall, antivirus, antimalware, antispyware, and other security software. Together with SafeShield, you will have a fortress of total protection
