Hi 
Actually many Avast users has same problem as you,you may try remove AIS in safe mode with aswclear and install it again.

Thank you.
Bye
PS:
How to uninstall our software using aswClear:
1:Download aswclear.exe on your desktop
2:Start Windows in Safe Mode
3:Open (execute) the uninstall utility
-If you installed avast! in a different folder than the default, browse for it. (Note: Be careful! The content of any folder you choose will be deleted!)
4:Click REMOVE
5:Restart your computer
I bought Internet Security version, and recently, as soon as I start my notebook,what AV did you usef before avast?......did your computer have a preinstalled trail AV when new did you remove it before installing avast? did you run the vendors removal tool to clear any leftover files that may conflict?
