Hi
I have Avast Premier running on my Win 10 Insider build 14951 (yesterday's update).
However, my Avast will not automatically update its virus definitions and is stuck on version 161013-1. It will also not upgrade to the most up to date version from the current Avast 11.2.2262. These issues existed before the update to 14951.
I have tried to update virus definitions from within Avast but get the errors of 'HTTP server error' and 'invalid file signature'.
I have tried upgrading Avast version but also get 'invalid file signature'.
I have downloaded the Avast installer for the most up to date version but it fails to install. Similarly, the downloaded offline upgrade fails - saying that sannot access the SXF Archive.
Any suggestions for solving this would be gratefully appreciated!
Thank you
