Personally I can every day submit undetected unknown but real viruses( not garbage) to Alwil ! and I will do this with pleasure , if these files will detected by Avast! next 2-3 days. But today I hate do this, because when I send real, serious viruses to Alvil these files are undetected by Avast! during weeks 
whyle other AV-s do this in 2-3 days, even in the same day!
And one very importan thing, will be very good to make virus submition more simple than send password protected file to Alwil via E-Mail.
There is excellent example how to do this easily: http://analysis.avira.com/samples/index.php
Oh yes, they ALWAYS answers to E-Mail (Alwil never
), good to know that somebody really care your activity :
