Update: I saw where turning off the setting “DeepScreen” would likely help with this because it’s purpose is to interogate those apps it doesn’t know much about. So, I gave version 9 (2014) another try, this time with that turned off.
That setting is in the main settings screen under the “Avast” category. I also turned off “Reputation services” right above that setting.
This solved it for me with Visual Studio. Also, I can run the .exe (my custom app) in Windows Explorer (Visual Studio not running), and the app runs fine. I’ve been running fine with Visual Studio now for a few days, with several reboots and Avast updating the definitions. So far, all is fine.
Give it another try with this setting turned off.
