Download Insight not analyzing certain files

Hello,

 

I have brought this up two times before, but not received any kind of satisfying explanation. No explanation at all, in fact. So, I thought I'd give it one more try.

 

How come NIS 2010 Download Insight completely ignores some .exe files?

 

One example would be the DC++ installer:

 

hxxp://downloads.sourceforge.net/project/dcplusplus/DC%2B%2B%200.762/DCPlusPlus-0.762.exe?use_mirror=kent

 

Another would be the video editor MkvToolNix installer:

 

hxxp://www.bunkus[dot]org/videotools/mkvtoolnix/win32/mkvtoolnix-unicode-3.4.0-setup.exe

 

Not a peep from Download Insight on either one.

 

These are both nice, non-malicious files, but who says the same thing can't happen on something bad?
