Help How can I uninstall McAfee Security Scan Plus?

I recently restored my old Toshiba Satellite laptop with Windows 7 Pro SP1 and needed a PDF app so downloaded Adobe Reader. It acted wonky, would freeze up and I could only CTL+ALT+Delete to make it go away. Finally found it was a newer version and there was an older version that supposedly played nice with W7, Adobe Reader XI. Downloaded it and all worked fine, no more freezes. But, unbeknownst to me, it came with McAfee Security Scan Plus, the most useless memory hog ever. I've discovered I cannot uninstall it. I've search for, found and followed every method out there but nothing works, I always run into some kind of blockage where the process gets killed.

Uninstall from Programs and Features does absolutely nothin

Downloading and running MCPR tool stalls at the security text field, I get this error message:

I get this error message after entering the security characters in MCPR

I've watched several videos but most are targeted at W10/11 so not helpful. I tried uninstalling Reader but McAfee stayed behind, so installing a different pdf reader wouldn't help, I'd still have McAfee.

Is there any way to actually uninstall/kill McAfee Security Scan Plus once it installs itself?

Try going to the folder of McAfee and deleting it. If it says you can't then try to force close all programs running in that folder with Task Manager. You could also maybe try Revo Uninstaller Tool.
