I bought a laptop, Lenovo brand. I uninstalled McAfee AV.
My older Lenovo laptop came with McAfee and Win 10. Against my better judgement, I upgraded to 11. The machine never ran right after that--very slow. I was able to deselect all GUI 'performance enhancements', and that helped with the speed issue. I was going to go back to 10, but the time for that had expired. They give you a month, I think. Thanks for that, MS.
In order to help the machine (I thought), I did a reset and new install, but inadvertently checked the 'keep my files' option. Once done, the machine ran better, but I noticed that McAfee was still an active process. However McAfee was not showing as an installed app, as I had previously deleted it. Evidently the company 'hides' their footprint, but like Freddie K., it never really dies.
I downloaded the official McAfee file uninstaller from their Website, and it showed that it was uninstalling all the McAfee stuff. However, once done, I still have a couple of McAfee folders that are somehow protected, and cannot be removed by a simple 'delete' command. And the process still shows in Task Manager. They really don't want you to remove their garbage.
I only use this machine to control my Tone Studio software. It's not connected to the Net. I'm going to totally reset it, which should (I hope) wipe everything clean.
I have such a low opinion of Lenovo, but they all add the garbage, so I can't single them out. On the other hand, I have always held MS is contempt, and I didn't think it would be possible for me to dislike a company even more than I dislike MS. But McAfee tops them. Together, MS and McAfee should share a special place in Hell.
If Tone Studio worked in Linux, I'd attempt that.
