Making Avast Home Edition running in background?

Somehow , Avast isnt running in the background cus you would see the icons on the lower right hand corner of your desktop.

How do i make this possible?

are you sure its not just that the icons are hidden maybe ? check tour taskmanager (ctrl/alt/delete) to see if avast program is active
look for ashserv.exe in your processes

Im looking in processes, what names should i be looking for?

Also, where can i go in program to enable this?

have you done anything that might have stopped the program running??
try a reboot and check for it to startup.
if no luck try to repair thru add/remove programs and hit repair instead of delete

I did repair, will that fix it?

do you see it running now?
