Using just Avast isn't going to give you a decent protection,you should also add MBAM in realtime for some reliable protection.
As for KAV is concerned,I am afraid its detection is not top notch these days so is Avast IS.
It is Norton which is making all the noises.
You should definitely turn on MBAM in your lappy,believe me you won't regret it.
The current version of SUPERAntiSpyware is nothing but a joke,it has always performed bad in all the known tests.
