Now it still seems to be disabled as there is no icon in the tray in Windows. Comparing the program settings to mine all is the same. What do you suggest I do to get avast active.
The icon missing doesn't mean it is disabled, only that the icon (user interface) is missing. What avast processes are running in Task Manager, they begin with ash or asw ?
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 or OnGuard), PrevX, WinPatrol, ProcessGuard, etc. ?
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). You will need to run this after each boot until the problem is resolved.
Check the option in the Appearance tab of Program Settings. Or Make a link to ashdisp.exe in your startup folder.
