McAfee just charged me $75 - Time Warner Internet

This question is about "McAfee just charged me $75", with Time Warner Cable internet and apps. I downloaded TWC's McAfee 2 months ago when I switched from my old internet provider. Yesterday I got an email from McAfee saying they charged my credit card $75 auto-renewal for another year of protection. I thought this protection was free for TWC Internet customers.
