Avast free17.2.2288 was updated to 2291 without user permission

Avast free17.2.2288 was updated to 2291 without user permission after update Window10 Insider1703(15063.0 to 15063.11).

Despite having set up Avast Program=Manual update.

I cannot use newest version2291, because the version is buggy(https://forum.avast.com/index.php?topic=199715.msg1382229#msg1382229).

There is no guarantee that something will work on a Windows insider build.
