The Norton and McAfee antivirus programs already control -- cal it "own" -- most of their market for antivirus prophylactic software. They've both been in the antivirus business for a long time and in McAfee's case from even before it was an actual business. This should give them both the maturity and confidence to move forward and lead the technology.

Unfortunately they behave more like competing sub-teen siblings; spending more time on "look at me, look at me" gestures and over-applying the cosmetics then on really focusing on being a competent and dependable tool.

The result, for both of them is that their antivirus programs seem to have become less reliable for the task at hand and much more of an irritating drain on user and machine performance. They are bulky and hyper-active and annoying to the point of distraction and this is all opening the door for competitors. Heads up Norton. Wake up McAfee.
