Well, KAV offers (multiple) daily updates. So new malware can be
detected earlier on systems.
But there's another point: Heuristics (KAV has got a special heuristic
fpr this worm) and unpacking (cause many worms are runtime packed,
crypted, patched, etc.). So it's a question of scan engine and signature
quality, too.
