AvastUI not running, no tray icon Avast Free 17.9.2322
« on: February 01, 2018, 03:56:44 PM »
Well, the Subject pretty much says it all.  The rest of avast free would appear to be operating correctly.

I have had avast free 17.9.2322 for some time and this missing tray icon started to occur a day or so ago.  I checked WinPatrol Plus and it shows AvastUI.exe in the startup programs (with a Command of AvLaunch.exe /gui) but it doesn't show its status as Running.

Manually running AvastUI.exe starts the UI and the tray icon remains after closing the UI, but it doesn't appear to run on boot, certainly not in the last couple of days..

Whilst I haven't noticed it on my win10 v1709 laptop, that isn't switched off at night, I just have it go into sleep mode after a few minutes. 

Having seen some others with issues on some components not starting up, I though I would check to see if anyone is experiencing this also.

I've already reported this to Avast. Appears to be localized to those running Windows 7.

I've amended the report to Avast. Now let's hope someone is still on duty and fixes this soon. :)

Thanks Bob,

I have just seen something else (possibly similar, but the old UI failed to load error) in the Russian sub-forum. However, I think that this is different as they are presumably trying to run the UI from the tray icon, which I didn't have.

I'm going to restart and see if it is replicated again.

I have the same problem. (Windows 7, only microsoft security packages are installed)

I observed this behavioir on 01.02.18 first.

I can restart Avast by typing the button "restart service". But some minutes later. Avast is still inactive.

I'm not sure this is exactly the same, other than the avast tray icon not being present, I get no other errors and the main avast service (AvastSvc.exe) is running. 

Of course if the avastUI isn't running in the background without the icon, then the display of errors could be a moot point.

OK, maybe you are right:

I made some Screenshots:
see attachments.

Can it be, that it is a problem with my third party Firewall? (I use this firewall since 4 years. Never had problems together with Avast. I only had to allow same rights (popup), when avast tries to make some updates from time to time. But until now it was never a problem.)

Simple solution is to turn off the other firewall and see if that resolves the problem. (Windows 7 and up you can always use the Windows firewall.)

Thank you for the hint.

Now, together with windows firewall and without my "well-tried" firewall, the issue is not appeared again.

But I want to use the other Firewall. Why does my old firewall suddenly not longer work?

You could try clearing out all Avast rules and have it start learning all over again.

This would not help. I have never forbidden any right for Avast with this firewall. All popups have been allowed.

Obviously something went wrong somewhere since things work fine without your FW.
