mcafee and itunes

this may be easy, but on the new mcafee security center what do i have to turn off so my songs purchased on itunes will download.  it keeps giving me a connection error and song won't download. i have tried turning everything off on mcafee to the point i'm thinking of uninstalling it, but then i will have no protection.. the old mcafee, i just disables privacy and it would work. help
