Possible virus pop up

I have Norton 360 and recently I started getting different pop ups such as the one I am attaching, and each pop up mentions captchareverse.ew.r.appspot.com within the pop up. I am thinking this is a virus. I guess some how I must have clicked on something I shouldn't have, but I must say I am usually very careful about the hazards of clicking on things. I am guessing this captcha thing is a virus and when I googled it everything I find is an invitation to download a program to remove it at a cost of some sort, and who knows if any of these programs will work or if they will just take your money. Anyone have a solution ?  I am disappointed that NORTON didn't catch this thing, I thought that is what they are supposed to do. I have run Norton scans, Norton eraser and have refreshed my firefox browser and all with no results

I hear ya'.  Just trying to help...long distance. 
I hear ya'.  You'd want/expect Norton to protect from all nasties.

I had an ad blocker installed on my laptop from the start 
I am still wondering why Norton didn't prevent this from happening

Care to share "ad blocker". 
Maybe, you allow 3rd party cookies?
Maybe, you allow acceptable ads?

Captchareverse.ew.r.appspot.com is able to spam users with disruptive pop-up ads through the following tactics:

  • Fake error prompts – The site displays system warnings such as “Your browser is out of date!” that urge you to “Allow Notifications” to fix the supposed error. This tricks users into enabling notifications.
  • Hidden notification prompts – Captchareverse.ew.r.appspot.com hides browser notification prompts in hard-to-notice places on the site to sneakily get users to enable them.
  • Redirects to the site – Your browser may have been redirected to Captchareverse.ew.r.appspot.com from another site or pop-up. This enables the site to prompt for notifications.
  • Software bundles – Some free programs bundle Captchareverse.ew.r.appspot.com software that enables notifications without consent during installation.
  • Social engineering – Pop-ups warning your computer is infected may link to Captchareverse.ew.r.appspot.com and tell you to allow notifications to remove the infection.
    [...]

Once the site has notification access, it can spam pop-up ads directly to your system tray or as mobile alerts. The ads are hard to close and lead to even more Captchareverse.ew.r.appspot.com tabs opening.

I forgot to mention that in addition to running the Norton Scan and the Norton Power Eraser, I also installed and ran Malwarebytes in an attempt to get rid of this thing and none of that worked either and by the way I had an ad blocker installed on my laptop from the start and apparently that didn't work either. I am still wondering why Norton didn't prevent this from happening
