Intel had been investigating selling Intel Security (nee McAfee) for well over a year, so this is hardly a recent development on their part. And regardless of what the Slashdot crowd things of the products' quality, they do have massive amounts of brand recognition in both the consumer and enterprise spaces.
Mr. McAfee had given up the rights to his name when preparing McAfee Associates' IPO and did quite well in terms of how he was compensated. Even back in 1995 he was already trying to get his name back from Bill Larson (then President, CEO and Chairman of McAfee Associates) and having no luck. As much as Bill hated the McAfee name, he realized there was so much money to be made in it, and took the company from $20-30M in revenue to billions of dollars in valuation .
Mr. McAfee's one of the smartest business people I know, and his ability to rapidly absorb data, synthesize it and come up with all sorts of ideas for products is pretty darn amazing, and frankly, with all of the time and effort he's put into being in front of the media, trying to get his name back at this point is a waste of time and shareholder's money spent on lawyers: Due to his recent high-profile activities, there's enough interest in Mr. McAfee that he doesn't need to capitalize on his name, anymore. He could name a company "Spicy Lemon" and still generate media attention because of his involvement with it, just as he's done with all the products he's taken on since returning to the U.S. after fleeing Belize.
