OK, a few weird things, now it is working with my download manager Orbit. Edit: I didn't use the %file% parameter as it doesn't seem to be required for ashQuick.
1. I downloaded via https to avoid the web shield blocking it.
2. The File System Shield detected it first (I have mine set to Ask) and I just said Block.
3. Then the ashQuick.exe detection kicked in, but all that does is give you an acknowledgement screen no actions.
So it looks like it works again, but doesn't indicate that the downloaded file has been scanned, and only displays if a detection is made, but no actions as in the normal avast detections.
