Not sure if this is in the right forum but the website VPS file version does not change and the current version is 081020 right? It appears as 081016.
I noticed that also… ???
The webpage updates are always behind the reality…
Trust in the avast update better than the webpage 
Thanks, Avast updated it self to 081021. I’ll check the home page…
EDIT: Now they appear correctly. 
The avast.com home page info is usually correct, the VPS version history page does on occasion take time to catch up.
