Intel + McAfee doesn't seem like a good fit. Also, McAfee's cash cow has been the Windows installs it effectively patches with extra "security". Seems like that market does not have a rosy future, compared to alternatives like Mac and Linux. So weird time to make a bet on the future of Windows security add-on demand.

Struck me a bit like when Ebay bought Skype. I had to really strain my brain to come up with a way that deal made sense.
