Extra pages opening when I click on a link or object

For instance, when I just clicked on the tab to post a new thread, the page popped up, but another page also opened. See screenshot. This one pops up frequently. Another that will open frequently is the second screenshot, but there's no rhyme or reason. I might click on a link on an item I'm looking at on Amazon to see something similar and that page will open, but an additional page opens.

Just now when I clicked on "Manage Attachments" that box opened, but look what opened on top of it (see screenshot 3).

This has been happening on any site I might be on, and on both my laptop and my desktop. I have the same browser, add ons, etc., on both computers.

I've had no reply to this. It's still happening, and in the past two days I've had one of those pages open that warn you that your computer has been locked up, etc. I've kept my cool, opened task manager and shut Google down that way, but I'm more than concerned.

What I was doing both times this happened is clicking a link to go to a product page on amazon.com. The product page opened, but this warning pop up with all the bells and whistles also opened.

Can anyone help me with this?

If you are using Google Chrome, click the three dots in the upper right corner, then "Settings", scroll down to "Advanced", click "Site Settings" and make sure "Popups and redirects" are blocked. If they aren't, change them.

That is already set to blocked.

When I clicked on "sumbit" to post the above I had another of those extra pages open. I noticed something at the top. Please see screenshot. I installed this extension just recently because I do all my shopping online and I thought this would be a good thing for me. But I think these page pop ups started about then. I removed this and will see what happens.
