C programs getting detected as Malware

Recently my C programs started to act weirdly and I had no idea why... Then I realized that they were being flagged by my antivirus program as malware... First I thought there's a malware in my compiler (I'm using CodeBlocks IDE with MinGW-GCC as c compiler), Antivirus scan returned nothing.

So I started experimenting on it...

I wrote a simple hello world using c

#include <stdio.h>int main() {    printf("Hello");    return 0;}

Soon as I compiled it windows defender flagged it as Trojan:Win32/Fuerboos.C!cl : Threat level Severe

So I uploaded the exe to VirusTotalVirusTotal results

30 engines flagged the file as malware...

Also gmail doesn't allow you to attach it as an executable file...

Is anyone experiencing this? Could someone explain this to me?
