Update avastui

hello,
I noticed this morning a development application “avastui” C: \ Program Files \ AVAST Software \ Avast \ avastui
last night was the version 9.0.2006.159 (as other known applications folder: ashQuick, ashUpd, …) and this morning after starting the computer: 9.0.2006.160
Is a tool available on this development? if evolution there!
thank you for your lighting
cordially

The main parts in the avast version/build number of concern are the first three elements, 9.0.2006 anything after that doesn’t require a manual program update.

These could be engine updates that are part of the virus definitions auto update and or as a result of the avast emergencyupdate checker to correct minor issues that don’t require a full program update.
