Check out the Whole Product Dynamic Tests results and you'll see Norton Internet Security lead the way with only .3% compromised:)
:offtopic: to be fair the exact score is : NIS : 99,3% + 0,4% User dependent , so it can also be 0,7% :.. and that's when AVC tested the whole product.:666:

The results above just show the proactive (generic/heuristic) file dection capabilites of the scan engines against 0 day malware.
From my experience Kaspersky has a pretty good heuristic engine and can detect a good ammount of malicious samples even if it dosen't have signatures for them
I never managed to play with G-data because for some unknown reason it always manages to freeze my system.
 
No surprise for Avira in retrospective test, they must produce a new version and for their FP its a low so next time they can make heuristics high at default.
