Suspicious.MLApp when build GnuStep application on Windows

[Joel]

I installed GnuStep on Windows XP. And my computer has Symantec Endpoint Protection which I have no control. The odd thing is when I use the example from website http://www.gnustep.it/nicola/Tutorials/FirstGUIApplication/node3.html

to create executable, I got error from the antivirus program about Security risk detected: Suspicious.MLApp. And the executable is removed automatically. 

Besides suggestion of change policy in antivirus program, my question is what causes a security risk when I compile the example code?  Is there any way to workaround by changing some code? My guess is the NSApp setDelegate somehow looks like a malfactor to the antivirus program. 

I tried to google the problem, but seems nobody reported that issue before.

Any suggestions?
