Under Windows 7 i noticed that if avast once is outdated an update doesn’t make the message from the action center disappear.
that means if you don’t install updates for avast! for some days until a message from the action center appears (that avast is outdated) and you perform an update (avast! shows the actual VPS version and date) the action center still shows avast as outdated.
only a reboot of windows can make the message disappear/let the action center recognize the updated version of avast!
(Tested with build 6956 - probably it already works under 7000, but i don’t think so)

EDIT: This topic seems to discribe the same problem.
