Ok so this seems to be a bug that few people already facing including myself ( Web Shield, Mail Shield ) been turned off after reboot, some people have different modules turned off.
Bottom line is that there is a issue in this latest version.
My OS is Win 7 x64
a repair. Do this by starting to uninstall Avast! via Windows, but choose the Repair option
It works for the first 2-4 reboots and goes back to the same thing, for me the next morning came back with thous 2 modules off.
