NUS 2011 new version download unproven

Hi,

 

I have NIS 2010 on my laptop.  I clicked to download the newer verison 2011 and got a weird message from Norton saying (yellow dialog box with issues).  I checked it and NIS said that this download had very few users, was very new, and was "unproven."

 

The website is as follows:

There was no suspicious activity and Norton checked it as safe; however, I decided not to download the file.  Could this file be malicious anyway?  Never happened before.

 

Thanks much,

Cody
