I gave up with McAfee years ago and for the same reasons. I have now been using Sophos for a few years and on the whole it's not been too bad. It found a few things on my old laptop that McAfee had missed. I have now installed it in a number off company's that I do support for and all seem happy. The only thing is that there is a minimum number of licences that you have to get of around 3 or 5 as they only like to sell to corporates and you have to purchase through a partner.
