Downloaded Adobe & McAfee installed no permission, and can't uninstall McAfee app

I was on my county's superior court site to get court forms, legit site. There was a link to download Adobe PDF to fill out forms so I can print out. I unchecked the McAfee Scan Plus box and clicked download. I was so mad when McAfee had downloaded anyways that I uninstalled Adobe, but McAfee would not uninstall. I called them twice both times. They wanted me to let them gain remote access to my laptop, apparently it's the only way the app can be uninstalled.. My laptop is running a bit glitchy and I'm afraid it McAfee all over again. Problems with them 2 years ago.

If anybody knows how to uninstall McAfee, please I need help.

Thanks
