Program won't execute

I recently got back into learning how to program C++. I used to be able to compile and execute code without a hitch. Now I am doing the most basic of programs:

Code:

---

#include <iostream>
using namespace std;
int main()
{
    cout<<"Hello, world! I love you!\n";
    cin.get();
}

---

First AVG classified this as a Trojan Horse and suggested I remove it immediately. I disabled AVG for the moment to go ahead and run the program again. Still nothing. I thought maybe it was something on my end. Although no errors came back when I compiled this, maybe I did something wrong?

Weird. Code is fine. Which compiler/IDE?

Check if AVG is running in the background (ctrl+alt+del) or as a service (administration tools). AVG is crap, but false warnings about basic programs doesn't seem right. Maybe the IDE debugger is flagging it, or something to do with data execution?

@Dae The main component of AVG isn't on, but there are several other processes with "avg" in the name.

When I turn off AVG and add

Code:

---

return 1;

---

after

Code:

---

cin.get();

---

it works just fine. No virus warning or error.

I am using Dev-C++ 4.9.9.2.

There is the other possibility -- you have a virus on your system, and it's infecting the compiled program as soon as the program is made. It's not uncommon for a virus to infect all executables that are accessed or created.

That is possible, but would have to be a very specific virus to selectively inject into his program and nothing else (anything else would follow more AVG warnings).

Seems to be a common issue between AVG and Dev-C++. Either AVG flagged Dev-C++'s debugger, or method of injection. Can't see it being a compilation (MinGW) issue, since there aren't any Code::Blocks / AVG issues.

Dev-C++ is deprecated (much like me). Rules of life:

1) Use Code::Blocks or Visual Studio.
2) Never use AVG.

It's almost certainly the problem. I don't use AVG anymore, having switched to Avira. But I had a similar hard to track problem with gdb for free pascal, early this year.

The attached DLL is not liking gdb. And being that Dev-C++ install a really old version of gdb, it's not surprising AVG code heuristics don't have any safeguarding for it. Newer version of gdb like those in Code::Blocks should have no problem.

BTW: You can add your whole project folder to the exception list of your anti-virus. You should add also gdb.exe. This if you want to keep dev-c++.
