Always allow an application

Is it possible to authenticate an application/exe so I don't need to press continue every time I start my computer?
My prob is that every time I start my computer I need to press continue to two Logitech driver exe's. That a bit irritating :)
And when I start Firefox, or if I click a link i e.g. outlook firefox need to be approved.
