Never purchase Mcafee

I have a few customers that were using Mcafee. Early December 2015 Mcafee pulled their support for Windows 10 without notice and left my customers stranded. After many promises to correct this issue I am still waiting for a working product. All I am told is there is a roll out queue for the new version but no ETA. Two of my customers have been unable to use a product they paid for, for nearly 3 months now.
