Asus Xonar U7

I have a Asus Xonar U7 external USB sound card.  I've downloaded the W10 drivers for it from the Asus site.  When I unzip them Norton goes mad and quarantines dozens of the files that form part of the package.  Is there a fix for this?  Surprised at this - Asus is hardly a small niche operation - why are its files considered a threat?

Thanks

Mike
