Ok i give example i send 10 days ago (1.1.2005) multiple infected files (viruses, trojans, malware etc.) ...
all of them were not ITW pieces
these which were most dangerous were added to VPS at 8.1.2005
rest still not ...
usually i send repeated request after 14-21 days e.g. asking why it wasn't added yet and very often i get good answer from Alwil team ... (e.g. sometimes files infected with trojan/virus/malware are damaged or similar and THEY NOT operational and these files Avast! ignore to report but many other AV keep reporting ... due to different detection scheme ...)
from my previous experience Avast virus research team uses layered system, first sorting viruses/trojans/malware by danger (ITW, non ITW, ZOO etc.) and then working on adding detection set into VPS ...
so delay is not just caused by time needed to analyse and implemented qualite dection but also by this sorting by importance of trojan/virus/malware ...
