hi steve42lawson,
I looked at the screenshot that you were kind enough to provide, and I really do not see a problem here. Sorry, but if the window in question says the virus update is up-to-date, it is up-to-date, and that is good enough for me.
As for the server error reported, it is just that, a server error. When something like this happens, it will take enormous resources at a company like Avast! to fix and resolve; it also will take a bit more time to deploy and push out the fix they are now deploying.
Think of what happens when you or someone else has a bad auto accident on a major city freeway; traffic will back up, emergency responders must arrive, and time will be needed to investigate the cause of the crash, victims need to be transported to the hospital as quickly as they can be, and only after the accident scene is cleared and fixed up, does the flow of traffic come back to a normal level.
EDIT: A multi-vehicle crash is even worse, so..
That is kind of what has happened here. Just so you know.
