McAfee does not want me to join that site. What is the catch? Nobody let’s you watch new movies for free.
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.
