I'm getting the update but it's sooooo slow. I guess that the Avast! server is suffering with a severe case of constipation.
Just my luck to choose this time to uninstall 7.0.1474 and reinstall 7.0.1466.
Avastsvc.exe kept crashing, behaviour which was unknown with 7.0.1466 on Windows XP. Trouble is that Avast! needs to down 70+ MBytes so this will take a while.
Anyone got a bottle of Syrup of Figs for the poor old server?
So first the Windows 8 issues and now we can't even update virus definitions, what on earth is going on with Avast.
I doubt I'll be renewing my Pro licence at this rate.

No problem here.
Windows 8 problem only effected some people. I have no problems on my 5 systems that are running Windows 8 Pro
That isn't the latest version, mine just updated to 121119-1, though it's still being flakey connecting to the server.
The latest vps version we will get is
121120-0, which is one version ahead of the one we now have. "20-0" refers to the date of the month and the version number of the vps update. Not possible to get this update from anywhere else other than directly from the Avast! server. The normal twice-daily vps update is incremental, and download size is in the Kb range. See below.
If you wish, you can go here to manually download the entire vps update now current for Avast! here:
http://www.avast.com/download-update I am now downloading that version; it is some 72.5 MB in size, as it is the entire definition update now current at this site.
Will update here in a minute or so as to what version this file is: 121119-1 See attached .jpeg below.
Note: Download speed is inordinately slow, in the 70-170 kb range, so it took ten minutes to download at this time.
