Clean Executable File Caught As Infected

when i execute .exe file from php , bitdefender caught the .exe file as infected ( but not if i double clicked it )

my .exe file is very simple and can't be infected (compiled with visual studio express 2013 )


#include<stdio.h>

int main(int argc, char* argv[]){

printf("Hello World!\nnumber of argument is %i\n", argc);

for (int i = 0; i<argc; i++){

printf("argv[%i] is %s\n", i, argv);

}

return 10;

}

and the php code that run the code is


<?php
exec('test.exe', $out);
echo '<pre>';
var_dump($out);
echo '</pre>';

i fixed it with add the directory to the excluded but i just wanted you to know that's there is maybe something wrong with the antivirus
