Hi,
I think the reason why mcafee websites are automatically placed in the trusted list is for facility... there have been issues wherein customer are not able to download the mcafee suite due to the fact that the browser setting is set to a level that won't allow some sites to be displayed... i think this would be a workaround so as for customers not to be bugged by security settings blocking customers from being able to successfully download mcafee...
If mcafee websites are in the trusted list that only means that you can visit any mcafee site without being blocked... though i'm not so sure why these sites are added ni the trusted list... but the best logic i can think of is that "with mcafee sites in the trusted list customers would be able to download and install their product from the websites without having so much problem to go through..."
