I personally dont like kaspersky,my opinion'too much bright things and not really action
But if you are happy with kaspsersky go with kaspersky.
Malwarebytes is one of the best.
In Crashes and Debugging
i found many bsod cases points to,
Avg,zone alarm,Mcafee,comodo,so try to avoid these,especially mcafee and zonealarm.
My favorite is Eset smart Security 5.
And for free system protection you can use this Good and Free system security combination.
Well,is always depends for what and how you use the system.
