When I open avast all I get is a blank page. I have just had to delete and reinstall avast because it would not update to the latest free programme. Anyone any ideas what is going on?

Hello, can I ask you to share with us following folders? You can contact me directly via email.
C:\Program Files\AVAST Software\Avast
C:\ProgramData\AVAST Software
C:\Users%USERNAME%\AppData\Roaming\AVAST Software
We are aware of this bug and trying to find a root cause of it, there is not better solution than reinstalling now.
I also get a large white blank screen when trying to open AVAST. This is happening on both of my machines. HELP
