Ok, with over 12 years in desktop and server support, I can say that McAfee has been a fine product. Norton was a very good second choice until recently. Norton seems to have dropped the ball several times. McAfee has never given me any problems.
More recently, I have moved to Kaspersky for my clients. I have not bee using it very long but it seems to do a great job. I will be installing the home user version on my system today or tomorrow.
Just my .02
