Avast antivirus prevent install of "Arduino AVR Boards by Arduino Version 1.8.3."

Avast antivirus prevent install of “Arduino AVR Boards by Arduino Version 1.8.3.” (Access is denied.)
Installation succesfull only after deactivation (for 10 minutes) of Avast Antivirus.

It sounds like you have solved it. Your system will probably behave like that any time you install any software.

I solved it after a couple hours on google. I almost decided to go back to version 1.8.13 of Arduino. I’m using Avast antivirus for Windows for years and it’s very unusual for Avast to deny install of a software (in fact this is the second time for me).

I post it here for Arduino developers to solve the problems with Avast antivirus denying install of Arduino AVR Boards for Arduino IDE 2.0.0-beta5.
