Argh. I have just spent the most maddening hour-plus trying to get rid of McAfee.
The article linked by @Tropical_Willie (thank you!) told me that I could not cancel the subscription myself but must go through Customer Service. A series of links led me in a circle right back to there. I thought of Alice following useless and confusing signs in Wonderland.
Finally I got hold of a phone number, which seemed in itself to be well-defended information, not idly imparted for the asking. After a long wait and then a quest through another menu tree (no relevant options, so I tried more than one in several iterations), I finally got hold of a person, probably someone in Bangalore, who told me…I could cancel it from my account page.
Nope.
After a long, frustrating process with her, I got transferred to Technical Support. The rep told me to shut down the computer, a process that itself took more than 15 minutes because all my functionality has been hijacked by these competing forces, and finally, finally, finally…
I got cut off.
Called back. Listened to a ringing signal for nearly five minutes and then got cut off again.
That’s enough of that for tonight.
