If you had Comcast they give you the McAfee free. I haven't had a problem with it - well thats not really true either. Today I downloaded their Privacy software onto my trading computer and when it did the restart to activate it the machine wouldn't restart. To be fair I have been having problems with that machine for the last week (it wouldn't shut off properly) and the Emachines tech lady told me today that the power supply died. We will find out if that is correct or not in a week when the new power supply arrives.
