I Download the files.avast.com/beta9x/avast_free_antivirus_setup.exe and ran the setup over the top of avast 8.0.1497 on my XP Pro SP3 system.
All appears to have gone well after first reboot.
So that was effectively an update of avast 8.0 to 9.0 without issue as far as I can see at this early stage. All settings appear to have been retained.
