I'm very sensitive even for smallest changes in my task manager which means I keep checking it everytime on startup and I noticed "aswEngSrv.exe" process stopped launching since yesterday. I even did a clear reinstall without any result of bringing it back. I also noticed that when I open UI by Avast icon from taskbar, two more AvastUI.exe processes are launching. When I close the window, one process stays. It disappears only when I shutdown pc. It's happening in version 19.8, didn't noticed that in previous.
