Permission Denied building CPP file in Visual Studio Code

Anwarjut67

When I run the below given code on Visual Studio Code, first Building it, but it shows:
> Executing task: g++ -g main.cpp <

d:/software/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: cannot open output file a.exe: Permission denied
collect2.exe: error: ld returned 1 exit status
The terminal process "C:\Program Files\Git\bin\bash.exe '-c', 'g++ -g main.cpp'" terminated with exit code: 1.

Terminal will be reused by tasks, press any key to close it.

I have Bitdefender Antivirus on the system. It showed an error describing "Infected File Detected", it detected a.exe file and after that I removed it from quaratine and deleted the file from there in the Bitdefender software but now I am not able to run cpp file.

#include <iostream>
using namespace std;
class Aclass
{
public:
int x = 0, y = 0;
Aclass() { cout << "constructor of Aclass" << endl; }
}
int main () {
Aclass b;
}
I tried some solutions from stack and other forums but didn't work, though other forums there is nothing much but on stack I found one with solution to turn ON "Application Experience", but unfortunately I cant find it on services.msc

Any help will be much appreciated. Thank You.
