I'm running Norton on a Win11 OS. I had decided to totally uninstall McAfee. It's all gone, except for 11 visible files that show in a program called 'Everything'. All gone except for 11 png suffix files. They defy uninstallation. Worse, a McAfee pop-up appears several times every day, and I use 'close window' to get it off of Desktop, but it always comes back later, saying I'm unprotected, and I need to buy McAfee again. I also tried the McAfee 'uninstaller' but without success. What can I do, please (and thank you in advance).
