Norton Internet Sec. 2010 detects C 'hello world' program as suspicious?

Hi folks,

The titile pretty much says it all. I did a fresh install of Windows 7 Professional, and installed a (legitimate) version of Norton Internet Security 2010.

I installed Dev-C++ afterward, as I'm learning C, and created a quick "hello world" program. This is the only code I had:

Code:

#include <stdio.h>
main() {

printf("Hello, World!");

}

That was it. When I tried executing it, Norton Internet Security 2010 popped up, saying its "SONAR" feature had detected "hello world.exe" acting suspiciously. I ran it anyway, and it executed as intended. I just brushed it off as a false-positive, but later I started wondering if it was something else. How prevalent is malware that injects malicious code in the source code of newly compiled programs?

Can anyone offer some insight, or if anyone has NIS 2010, can you try the same thing to see if you can replicate it?

Any help is appreciated.

Thanks!

 

Eh ignore the incorrect code, should be void Main()
