Hello there!
I was playing around with the code below(it's in the book I'm learning C++ from)...

#include <iostream>
     
using namespace std;
          
int main()

{
     cout << "Hello Univers!" <<endl;
     cout << "Test" <<endl;
}

...added another line(with red), when I pressed F9 to compile it, antivirus pop out saying it's a virus(not a big deal, I just wanna know why it happened).

Why?

Antivirus: AVG 2015 Latest Version.

You should send this report to Anitivirus authors, not on AlliedModders board .

He's asking why antivirus thinks that code can be malicious, talking in a programming way

Since we don't know what it detected it as, who knows

I heard that some antiviruses have terrible condition for detect "malicious files" — small size of executable file . And I think it's same case.
We have clean executable (if some virus not "infect" file instantly after compilation). So, we can't apply any signature to this.

@Phant, Send this report to some million dollar company with more than 110 million customers worldwide and wait 2-4 months until they see it and reply again.

@YamiKaitou, It detected it as a malware that can steal my computer history!

I remember two times when Avira has detected a virus callled "hlds.exe" just after some steam updates (problem was solved in the next steam update, 24 hours later).

my computer's history starts from before the stone age, fortunately it's also available in some external drives.

They just think that program was made by some kind of weirdos, just by searching for such words: "Hi World" and "Hello World". Furthermore, there is no version as an attribute for the project, I guess. So no author, no date and no version - of course not a signed code.

Have you tried www.virustotal.com ?

What kind of malware? What was the exact detection method (you can check your logs to see it again)

@ANTICHRISTUS, I thought that 2015 after the name AVG was going to fix all the bugs the antivirus has.

@claudiuhks, just tried it and it wasn't detected as a virus.

@YamiKaitou, can't find it, last thing registered is an update I made two days ago.

In the moment I pressed F9 there was a window that usually pops out when I download some virus(it opens automatically), it automatically scans everything new in the computer.
