Avast One Essential and Windows Security

[Mateusz99]

Hey,
after reinstalling Avast One Essential I noticed that Windows Security tray icon disappeared and I can't turn it back on. It's enabled in autostart. Is it expected behavior? I don't remember it happening in the past with Avast One or other AVs.
Thanks for any response

When a third party antivirus is installed by the user, Microsoft Windows disables the Windows Defender antivirus to avoid conflict.

Now, I don't use Avast One Essential (but Avast Antivirus Free), but the same should happen.  I don't know why it would have been an auto start entry after a 3rd party antivirus is installed.

I also use Windows 10, but it should be the same in Windows 11.

I used Avast Free Antivirus and Bitdefender Free and the Windows Defender tray icon was on taskbar. Even used Avast One Essential in the past too and the icon was also there. So because of that I'm surprised it disappeared now. But when I open Windows Defender app it says everything is working so I guess it's how it's should be

I have never seen the Windows Defender Tray icon, so I don't know why this is and why it was introduced.  I have been using Avast Free for 20 years.  Way before Windows 10 came along and when I switched to windows 10, I installed Avast immediately. 

Now elements of Windows Defender may still be present (when you install a 3rd party AV) as you can choose to have it present to run on-demand scans and presumably also keep its virus database updated.  But I declined the periodic scans option, so never saw this Windows Defender tray icon.  I just wonder if that icon were to enable you to run an on-demand scan. 

Do you mean the Taskbar on the left or the Toolbar on the right  ?
In windows10 I have been able to send the Windows Security to the Taskbar on the left (Different presumably to Windows 11s Central location.

OK I have just seen this in the Avast Antivirus side of the forum and Avast One would probably have some of the same code under the Avast One skin, it might apply.

<snip quotes>
Hello everyone, please let me inform you that yesterday, we finally found out what is causing the issue so let me share some key points:
* the problem seems to start with 23.3 version (23.2 and lower seems to be ok)
* the problem is somehow connected to our security network driver aswNetHub.sys - when not loaded, problem does not occur

Now, hunting what exactly is causing the issue and fixing it could be longer (not much changes went to this driver recently, so it could be something related but not directly connected) but bug is recorded and colleagues are looking at it. Will keep you informed about it.

Have a nice day

Hopefully this bug when found exactly it happened is resolved would also be applied to the Avast One side.

Thank You for linking that. So looks like I have to wait for Avast to update then

You're welcome.

Essentially until a resolution (and patch) is found you would have to manually open the Windows Security if you wanted to run a scan.  But with any on-access antivirus (like Avast) the need for on-demand scans is much depreciated.
