Usb Immunizer


I've got a question about USB Immunizer, it's a free tool that you can download from the 'Toolbox' from Bitdefender site.

I don't really understand what it does, does it blocks virusses that maybe is on you usb if you put it in your computer? Or does it blocks the USB itself?

Also I don't understand how to use that tool.

A next problem is that I downloaded the tool and I always need to go where I saved it, it has the name BDUSBImmunizer Launcher?! Why it can't be installed in the menu of your Bitdefender?

I hope I get some more information.
