Button to scan File names with spaces

I have created a button to scan files swith Norton AntiVirus.

D:\Programs\Norton SystemWorks\Norton Internet Security\Norton AntiVirus\NAVW32.EXE %1

Now this works on a file name with no spaces i.e. "test.zip"
My problem is with a file name with spaces i.e. "file test.zip"

What Argument is needed to achive a scan that will include the whole file name with spaces?

Thank you,
grant
