Mcafee popups on my computor.
McAfee popups come up on my computer every time I log on to subscribe. I don't have McAfee. Also Antivirus license expired warnings as well. I have tried everything possible to stop this. Very annoying. I have gone on YouTube to watch videos on how to prevent popups from happening. Nothing is working. I hope you can help.

You can check for recently installed suspicious or unknown extensions.
Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.
- switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can do a malware scan just to be sure.
