Starting Avast from Explorer directory

Hi
I have lost the rotating ball in the system tray which means that my comp is not protected - Avast not active. The 'Hide inactive icons" - for System Tray - is unchecked.
Apart from rebooting, I don’t know which .exe file to invoke in the Avast directory. It would be convenient to do so without a reboot. Anyone out there that can help?
Eric ???

You can:

  1. Reinstall avast or repair the installation (Control Panel > Add/Remove programs > avast > Repair)
  2. Run ashDisp.exe from the avast folder and see if the rotating ‘a’ comes back 8)
