thats nothing to be ashamed of.

The engine of avast will improve. Every update improves the engine a little

I agree with MacLover2000,but i’ll just add,that Polymorphic viruses are the most complicated pieaces of software compared to other “destructive” software. They are very hard to detect.
avast! will most certanly improve on this field as it did on others.

These are not ItW viruses – e.g. they’re not among people.

We don’t really bother much with adding some historic, laboratory viruses just for the sake of getting higher scores in the VB tests.

What counts is the ItW viruses – and this is where we usually score very well… :slight_smile:
