I have worked with computers with McAfee and Norton before and found them both very irritating, but that was back in the ninties, I suppose it is possible that they made improvements since then. I always judge my virus software by whether or not I can tell it is running, if it makes itself obvious then I don't want it, if it is doing its job behind the scenes without bother me, then I am happy with it. So far AVG has done a good job of working for me and keeping quiet about it.
