[Mingw-users] antivirus detects hello world executable as trojan

[Andrew R. <ar...@ge...>]

Let me start by saying that I'm a total newbie to mingw
I recently installed mingw 5.1.6 on win XP sp2 using the GUI installer

To test it I compiled the following C code:
 

/*Program starts here*/
#include<stdio.h>
main()
{
            Printf("Hello World");
}
/*Program ends here*/
 

I compiled with the following command:
g++ hello_world.c -o hello_world.exe

That worked fine, a "hello_world.exe" file was produced.  When I went to
execute the "hello_world.exe" file, I got a warning from the Avira
antivirus software I have running on my computer, saying that
hello_world.exe is the TR/Rozena.feb Trojan.

Has anybody else run into a problem like this?  Should I be concerned?
Is there a way to test if the GUI installer is compromised, say via md5
signature?  

BTW, scanning the installer or the installed files in C:\MinGW (with
Avira) did not turn up anything.

Thanks in advance for any advice you may be able to provide,

Andrew
