Yes if you look thru the Virus area where we talk of AntiVirus solutions you will see Norton and McAffee are not high on many people's list.
They use to much resources and bog down your system. Let alone are incompatible with 50% fo the software out there and break the other 50% of the applications.
It is always advised to use something better. Avast!, NOD32, or AVG are always the first to be suggested. Avast and AVG the free versions work 300% better than Norton or McAffee. So it isnt saying much for those apps when a free one works that much better.
But those are also some top rated AV even being free.
