That's a good question housi...
I've noticed the VDB is still dated 11.11.04 also.
I'm eagerly awaiting an update to see if Automatic Updates is working.
(I believe there is a problem with it).
Eventually, I can't stand it anymore and check manually. (Which works fine by the way).
Still, just checked a minute ago and it said my 11-11-04 DB was "already up to date".
When I uses Avast a year or so ago it seems there were updates sometimes even more than once a day.
Maybe the Virus writers are on vacation?
