Avast! Team is probably trying to work this out as quick as possible anyway, so give them sometime.
I know that Avast! Antivirus on-demand scanning isn't the VERY best compared to others, but it is one of the top choices. On the plus side, resident scanning is way better on many aspects.
I'll say give them some time. But on the subject of computer security, time is ticking ... Hurry Alwil !!
