Looking at your VT link doesn't show Avast for Windows having timed out. The only thing avast related was Avast-Mobile and that didn't time out "Unable to process file type" which is also different.
But as said, these are not the same as the actions on your system they are an on-demand scan engine located at VT.
By the time I checked your VT link the results were over 4 hours old, so I refreshed the scan and the Avast (for windows) scan was completed relatively quickly whilst other scans were spinning their wheels. But as Pondus said this is something you would have to take up with VT.
