Avast IS cannot update engine or virus definitons. I’m running Windows 7 SP1.
Current version 2015.10.2.2214 but 2015.10.2.2215 is available.
On attempting to update, the following message returned: unknown error; already up to date.
Anyone any ideas?
Try avast repair
Controlpanel > Ad / remove programs > avast > uninstall / change > repair option
Did that change anything?
Or perform a clean installation of the latest version (advised)

2215 is also outdated, follow the instructions in the earlier posts for a repair and if that fails a clean install with latter 2218 https://forum.avast.com/index.php?topic=169887.0
Apprecite the helpful responses.
Repair threw an error but clean install woked a treat :).
Issue resolved. Thanks!
