I recently reinstalled NIS 2010 on a Windows 7 64-bit system. When I download various files or programs, I seem to get a lot of yellow or caution warnings from Norton about the file I just downloaded. When I click on 'more information', there doesn't seen to be anything wrong that I can tell. I have another computer running on Vista and when I download the same files, they seem to be always green. Any help would be appreciated.
