BAV,
Go into the Start Manager and look for the process ashdisp.exe
This file generates the icons for the tray. If you do not see it there, then go to the Control Panel/Add-Remove and find Avast. Double click on the Avast line and an options menu will open. Find Repair and double click it to start the Avast repair. This should fix things.
If not, come back and let us know.
Good luck
