Constant Pop-Ups

It seems I went to a bad website and now I’m getting constant pop-ups about viruses. I keep clicking ‘Delete Viruses’ but they just keep coming. This has been going on for half an hour now.
I’m using the free version.
Thanks for any help.

Alright, my bad. I just noticed the pop-ops are from McAfee but I don’t have McAfee installed on my computer. It’s not in the Uninstall/Remove list.
How to get rid of it?

There really isn’t much to work with.

First a screenshot of the “constant pop-ups about viruses” might help.
Have you any browser extensions, security add-ons that might be responsible ?
