Avast doesn't let Skytest program

Avast Free Antivirus / Premium Security
1

My Avast antivirus 20.8.2432 doesn’t allow to open Skytest program. No any alert or notification of a threat. And I am sure Skytest is safe and virus free.
When I remove Avast, Skytest works with no problem.
This is link of program. https://www.skytest.com/DLR-Test-Preparation.htm

Any ideas or solution ?
Thank you.

That menu is not available for me. Because no shield installed.
