After a long tine i've found a easy solution for installing AVAST silent and prevent the background-installation of Google Chrome

With a simple registry trick i prevent the execution of "aswOfferTool.exe" that want install Google Chrome or some other s***.

Just download the actual version of Avast Free AntiVirus direcly from avasts website.

Paste the following code in editor and save them with the specified names.

Name: settings.reg

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\aswOfferTool.exe]
"Debugger"="logonui.exe"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\GoogleUpdate.exe]
"Debugger"="logonui.exe"

Name: settings-off.reg

Windows Registry Editor Version 5.00

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\aswOfferTool.exe]

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\GoogleUpdate.exe]

Name: inst.bat

@echo off
regedit /s settings.reg
start /wait avast_free_antivirus_setup /VERYSILENT /NORESTART /SP- 
regedit /s settings-off.reg

This is quiet easy and you can use the original installer you've downloaded from the website.

Questions?

Happy installing

Works perfect thanks will try it on Avast IS

Tested and working on a VM a few days ago. Is anyone aware of other switches that further customize the setup, for example choosing which shields (not) to install?

Cheers

thank u so much for help

it worked here

anothe qu.

how can i make the silent installation use another language , i know that the switch is ( /instlang ) but where i can add the laguage i want to ?

hello ,,any answer please ?

You don't need to add the switch instlang.

Avast installs alway the language read from system.

If you have Windows in Italian - Avast will install in Italian too.

Additional languages are unimportant and not so easy to install in silent-node.
