I've tried everything including the vpsupd.exe and it's still cutting out on the scan. AVAST says they are in the process of sorting out the database issues so let's hope they do because, up till now, I've been very happy with AVAST...will give them a chance to sort it but they really should be more forthcoming about the problems. Like put up a public message saying what they're doing to sort the problem and when it's likely to be put out or uploaded.
