Got the new license key to re-register the free home version BUT nowhere does the “blue a-ball: appear in my system tray” which apparently is needed to input the key. I also do not know how to access the “simple interface” in order to select “help.”
avast! icon missing - As a temporary measure until this is resolved you can create a desktop shortcut for this file C:\Program Files\Alwil Software\Avast4\ashDisp.exe (the avast icon and interface to the providers). Right click on the file and select Send To, Desktop (create shortcut).
What other security based software do you have that might block new startup entries, e.g. Spybot S&D (TeaTimer), AdAware (AdWatch), SpySweeper, Spyware Doctor (StartUpGuard), PrevX, WinPatrol, ProcessGuard, etc. ?
Check the option in the Appearance tab of Program Settings. Or Make a link to ashdisp.exe in your startup folder.
What avast processes are running in the Task Manager they begin with ash or asw, see image ?
