Why you can’t trust John McAfee’s tech support video advice

By now, you’ve probably all watched (with jaws agog) the NSFW video where John McAfee describes – with the merest hint of sex and drugs – how to uninstall McAfee Antivirus.

It’s been a couple of decades since John McAfee had any affiliation with the company which bears his name, and it’s possible that his technical support skills have got a bit rusty in the meantime.

Take this screen capture I made from his video, for instance. You can find it at 3 min 21 seconds:

Mac OS X running on a Dell laptop?

Neat trick. But probably not a combination being used by many McAfee Antivirus users I’ll wager.

  1. You know since you left Sophos.. too much free time at all? :)

    1. Well, this is only my second day after leaving Sophos.

      So far I'm doing fine, thanks!

    Everybody knows that you can run OS/X on just about any x86 Intel based computer, as long as your video card is supported by OS/X. Obviously, that requires a hacked version of OS/X to do so and that make me wonder on the subtlety behind that fact. Does he wants to look like a hacker or a pirate?

      My thinking was that it's more likely the marketroids who prepared the material for the video created the screenshots on a Mac, and chucked them into something like PowerPoint to display them on the screen.

    Funny, I had to allow noscript to perform an XSS in order to submit comments. Strange behaviour for a security site, don't you think?

  4. Hello,

    I think it is really important to understand that this video was made to have a little light-heated fun, rather than to be an actual guide to removing John McAfee's namesake from a computer.

    The video was originally shot with the laptop off, and the screen added in via chroma key later.
