Help with install options.

The subscription to my Avast 7 (free) will soon expire, so I guess it may be time for an update to v9. I would be very happy if someone would take time to write which possibilities I will have during the installation, so I can be prepared. Which program parts are selectable (shields ect.), and which are not? Which non-Avast stuff is included, and how can I avoid it? Have anyone tried the boot-time scanner in the newest version?

As you are upgrading from V7 I would recommend that you run a full clean install

Download Avast Uninstall Utility to your Desktop.
Download the correct version of Avast
Avast Free
Avast Pro
Avast Internet Security
Avast Premier
Disconnect from the net
Uninstall Avast via control panel

[]Run the uninstalltool and accept the reboot to safe mode
[
]Once complete reboot your system
[*]Reinstall Avast


Then select custom install and deselect any elements that you do not want from the list
