windows security stopping my modem driver from loading

Hi,

I installed a modem in my dell 410 and downloaded the vista drivers from

usRobotics. At start up, window security blocks the exe. programs from

loading until I okay them to run. Vista does this eveytime at start-up. Does

anyone know how identify these to windows security as being okay?

Also, after I get by windows security, user acct. control stops the drivers

from loading and asks for the admin. to okay the drivers loading. How can I

get the modem drivers to load without all the hassle.

Thanks,

Terry
