Are there any processes visible in Taskmanager starting with "ash.." and "asw.."? This would indicate Avast is working. Is the blue ball in the system tray? If you left click on it and select "standard shield" does it show the scanned count?
All these present indicate Avast is operating correctly, in which case you may need to reset the security centre, post 5 by yours truly.
Here's another reference.

Sometimes, Windows Security Center stop recognizing your antivirus or firewall... So, check your system time and date and also http://forum.avast.com/index.php?topic=23457.msg193534#msg193534

Problem is after update SP2 and no other scanner program at startup ,
I use Windows firewall only .

After problem my computer  disable alert.

Really I am not afraid about this problem,but if program common running is best.

Did you reset the security centre?
(Not a bad idea. Not difficult to do.)
