Computers that I have been on that had McAfee and Norton were always the biggest pain in the butt, difficult for inexperienced users, and reacted to the weirdest things.
I am sure McAfee and Norton are probably good protection software, but I don't use them, and never will.
I use FIREFOX, have SPYBOT, and AVG (for free) and have never had a problem.
Maybe you should see what someone else who has McAfee says about their experiences.
There was a signup page with a form and that was the page that Mc said don’t go there. I could not get a movie to download from the front page. Probably just my computer ignorance. Thanks for the reassurance. My computer saavy son put McAfee on for me and said it was good. I’ll get him to show me how to get the movies.
