Download avast! External Control clicking on 'Control' in my signature.
Unzip it and run.
You'll see avast! tweaker option.
Choose to show system tray icon and let us see if it helps.
Another way to fix the problem, just add the path to ashDisp.exe into
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
(as the value named avast!).
Are you by any chance using spysweeper?
If so, use the restore/recover or whatever it may be called to restore the deleted registry entry and update your definitions file for spysweeper. It reports incorrectly (false positive) the avast ashDisp.exe which is the icon you see on your system tray.
For the 'i' icon (VRDB):
http://forum.avast.com/index.php?topic=14356.msg121337#msg121337Fix tool for missing tray icons. Download it here:

Run it and just click Fix button. Log off and log in again or simply restart your PC and icons should be back again. The program is standalone extract&use (although it looks like installer).
