Whenever I do programming on my own laptop, because I have Avast installed, every time I try to debug a program I get the above pop-up appear in the bottom right of my screen. The debugger doesn’t attach, and the program attempts to run for up to 15 seconds, before Avast decides it’s actually OK to run, cancels the program, and then restarts it attaching the debugger. This is very annoying.
How to fix
(Update: Thanks to @AlecOstrander for pointing out that Avast has updated the location of the settings, I haven’t updated my pictures here)
Open Avast and click Menu then Settings found at the top right of the screen.
In the settings menu, under General, there is an Exclusions section.
Click browse and navigate to the folder where you store your Visual Studio Projects and select the tiny tick box next to the folder. Then click OK.
Now click OK on the Avast Settings.
When you debug your Visual Studio projects now, you will not get that pop-up that is scanning the .exe file, and the debugger will attach without any issues.
