WSA and Visual C++

I'm just starting out with WSA.  I've found that it detects programs that I build with some versions of Microsoft Visual C++ (but not all of them?)  as threats.
 
For example, a simple hello world program is detected as "Vir.Tool.Gen" if built with VC++ 2005 and as "W32.Hack.Tool" if built with VC++ 2010. But no apparent problems with the hello world programs built with VC++6, VC++ 2003, VC++2008 or VC++ 2012.
 
Is there a reasonable way to whitelist the output of programs that I build?  I generally build my programs in one a few directory trees; for example, several projects might be underneath c:devtrees. 
 
Maybe I could tell WSA that unknown programs anywhere in c:devtrees are not to be considered threats?
 
Thanks
