Driver for USB Software security Key To those that are all up-tite about it installing -- well windows somehow has to install the driver in order for the machine to read the data on the device - if windows didn't install the driver windows would not be able to access the stuff on it. As for the installed without my permission ... ya plug in a plug & play device windows recognizes the new device & installs the drivers for it to work. Completely normal.
It is running in the background keeping CPU 100%
