In many cases it might be impossible to create your own user account or others gain unauthorized acces to your account by password mining etc. ProtectX keeps your data safe because ProtectX must not be installed on the system. You may use ProtectX on an USB stick simply by doubleclicking the executable file. Leave the application and its data on the stick. Nothing will remain on the target system. ProtectX seems to be only a little Windows calculator but it is much more. By simply entering a hotkey combination a new window will be opened, providing numerous additional functions.
