Tray icon won't respond

Avast Free Antivirus / Premium Security

When terminating Windows Explorer and then manually re-running it, AVAST tray icon won’t respond. No UI nor context menu.
It happens in other cases as well, but I couldn’t reproduce them.

Terminating Explorer from the task manager effects a lot of things and not just the avast tray icon, does it impact on other tray icons ?

If you restart avast from the Start button > Programs does it resolve this ?

Have you tried an avast Repair ?

My other tray icons respond normally after re-running explorer.

It happened after a clean install. I haven’t tried an avast Repair. I activated AvastUI.exe manually.

Thanks.
