Is this MALWARE?

A couple of times recently I got a screen in FFox that looks like the one below...

I first clicked on the "Technical Details" link (blue text).
FFOx instantly gave me a warning message about the page.
That did not show in this screen grab!!

Obviously, I declined. This shows up as a NEW WINDOW in FFox after a Google search (sometimes).

I did a search on "firefox safe search incognito" and amongst the results I got this one below:

Has anybody tried to install it? Has anybody verified it is malware?

If nothing else, LOOK OUT/Be AWARE.
