G-DATA 2014 as with 2013 gives you an option to run with (A)&(B) , (A), or (B) so technically engine (B) would give you a really low detection rate on its own, where as it would have been Avast! before. I did a test of Avast! on my 100 files just for interest and it detected 79 of them which is pretty good as they were very new files conspired to the new (B) which only detected (3), I would rather the Avast! engine any day.
