You would have to create a desktop shortcut (right click on the ashDisp.exe file, select Send To (Desktop Shortcut) and double click this each time you boot because running it is only a temporary solution.
You didn't answer Tech's question about other security software as this is a classic for removing the avast icon. 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.
Or Add the path to ashDisp.exe into a value named avast! in the Windows Registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

So i have to re-down load the software...theres no a way to simply turn it back on without the blue ball?
You don't have to re-download the software if you still have a copy of the setup file on your system and you don't need to re-register if you still have the email with your registration key. During the time we have been trying to enable your icon, it may well have been much quicker to uninstall, reboot, install, reboot as Tech suggested earlier and probably much less complex.
