Norton is far better than many are giving it credit for quite honestly.
Only thing i hate about it, is that Malwarebytes has nothing to do ... ever.
But I guess thats a good thing.
As far as Sonar, mines only went off 1 time.
On further investigation, I found it was correct and done the right thing.
Just curious, In what way is it suspicious? from my experience with it, it only chimes in if something is happening thats potentially dangerous or actions that are not at all normal.
