Hi Sun, and welcome. The info in this thread by Bugbatter may help you:[URL]  
Today the Mcafee software point out that I need to pay for a official version. But when I bought the New 15R, the order includes a "15 months of McAfee software period of use". So I don't know why I still need pay for it. Or does anyone can tell me how to figure it out? :emotion-39:
The question about McAfee! I already buy the software!
