will alwil ever come out with an avast online scanner like kaspersky, comodo, panda, etc?
Good question. Actually, there is a very very limited on-line scanner for files only.
Yes, it would be nice to have an good Avast Online Scanner Service
Did you notice that a-squared is adding an AV engine? They have a USB version etc
It would be nice to have a USB stickable / CD ready version all zipped up and on line
implies up to date definitions
Where… a link please 
the stick is
a2usb.zip and is free

The AV version is in their beta
they have “integrated” (kludged) the av and AS together not a total rewrite a la Vipre
i agree.
