Downloads

I am running Vista on a HP Pavilion m9457c-b. I have NIS2009.

 

I want to know how to check a downloaded program with NIS. I put the installer is a file in my documents. When I was using a Computer Associates Security program, I could right click the file and "check with CA" would be in the drop-down box. I would click on "check with CA" and it would scan that file and tell me if the file was clean. Am I able to this with NIS and how do I do it.
