No problem.
It wasn't so much a suggestion to download the full database, more to show that between avast 8 and avast 9 the VPS function changed. That would probably impact on how it is compiled, delivered in the avast 8 installations.
New signatures may well be in avast 9 but not in avast 8 because it doesn't have the background avast scanning functionality to use the new signatures. But it is certainly weird.
