Avast Secure Browser do not open

[Christian247]

Hello,

I use Avast Antivirus since many years and Avast secure Browser too. Last day, i update the viruses of the anti virus and then i ask it to reboot my windows PC to make an inspection. No problems with viruses. The only problem i encounter is that i can open the avast web browser anyway.
I have tried to reinstall it many times but nothing works.
I have the last version of avast free software, as :
-version du programme : 23.10.6086(version 23.10.8563.800)
-version de la base virale : 231028-2
-Version d'interface : 1.0784

What is the problem with the browser ?
I have also tried to close avast and the firewall associated, but with the same result ....

Thank's a lot for your suggestions
Christian

Hi.
Do you have a cleaning program?
(like avast cleanup).

You must uninstall the browser, to pass the cleanup and to restart.
Then install the browser..

try that.

Hi Chrstian247

Please try to use this tool to fully uninstall Avast Secure Browser and install it again.

The Avast Antivirus should not block you from using the browser.

thank's a lot for both the 2 responses i have got,

I do not have a "avast cleanup" but i have already uninstall and reinstall avast web browser many times, with administrator privileges.
But the browser doesn't want to open anymore.
Is there any log files i can inspect to have an idea of the problem ?
I have already try to desactivate the avast antivirus and the firewall, thinking it was a filter rule somewhere into my Windows 10 pro system but i have got the same result. The browser doesn't want to open !!!
I haven't any idea where to search
Thank's for your attention

Can you please check task manager when you are opening the ASB? Can you see the processes?
Also the remove tool do more complex cleanout of the Avast application so it is not the same as the basic uninstall tool. So feel free to also try it for one more reinstall.

Clean install of the Secure Browser:
Maybe it's time for a clean install of the Secure Browser
Download the installer from here, https://www.avast.com/en-us/secure-browser
Download the Secure Browser Removal tool from here, https://download.avastbrowser.com/avast_secure_browser_uninstall.exe
Save your Bookmarks via the Book Marks Manager if you have custom bookmarks so you can import them when you re-install.
Uninstall Secure Browser via Programs and Features - Reboot
Run the removal tool, reboot, run the installer import your favorites if you saved them.
A video to help with the installation: https://youtu.be/r_VLA0HMLQM
Report back if that's solved the problem or not.
Avast has offered a separate tool to totally remove the Secure Browser if the above instructions don't work.
You can find that tool here, https://forum.avast.com/index.php?topic=230288.msg1531315#msg1531315

thank's a lot for your answers. I have done what you have told me but the result is always the same.
It is more complicated than only desinstalling and reinstalling the browser.
There is a problem, perhaps with some permissions and/or firewall or others, i don't know.
I can't show you the windows tasks because the copy/paste doesn't work with this forum, but this is no avast secure browser task running anyway.

Thank's for your supplied.

Copy and paste it into a .txt file (if text) or save as a (.jpg/.png/.gif) if an image you are copying and attach that to the post.

Hi.
you have to clean the "remains" that remain when uninstalling.

you need a cleaning program
if you search online, you find them for free.

if you don't clean the remains, uninstall and install,
not going..

Unfortunately, if you fallow all deep clean guides mentioned in previous topics and if there is not even brief show of the browser process in task manager, it looks like a more deep problem with the operating system, resulting in not starting processes.

[Christian247]

Hi,

This are the screens i have taken today after uninstalling avast secure browser, applying cleaner and reinstalling the browser.

The result is the same

Can you please send me version of the browser?
You can find it under:
c:\Program Files (x86)\AVAST Software\Browser\Application\AvastBrowser.exe -> Right click -> Properties -> Details

Thank you.

I checked this version and on my side it looks fine so it is not version related.

Can you please use these steps and check the logs?
Run browser with this command-line: AvastBrowser.exe --enable-logging --v=2
