System tray icon is not showing

Avast Free Antivirus / Premium Security
1

I have no icon in system tray but I do have processes that I see in task manager (ashMaiSv.exe,ashServ.exe,ashWebSv.exe,aswUpdSv.exe). I did run some very aggressive antispyware tools, against some very aggressive malware (witch Avast didn’t detect).
(Avast 4.8, home edition, + windows XP Professional)
If anybody has any any ideas I would appreciate them, if not, I’m thinking of reinstalling.

  1. Check the option in the Appearance tab of settings.
    or
  2. Repair your avast installation through Control Panel.
    or
  3. Make a link to ashdisp.exe in your startup folder
    or
  4. Add the path to ashDisp.exe into a value named avast! in the Windows Registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

If that does not help, please, uninstall, boot, install again, boot.

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.?
