I only have the problem on one particular site I use and to further compound the issue it always asks you everything twice. You click the pictures with e.g. boats in and click ok and then it makes you do it again. I noticed a link on the page which said something like "why am I seeing this" and I clicked on it and was redirected to another page. There was a load of blab about antivirus settings, malware and vpns and there was a link to a browser extension you can download from the google store which bypasses it. It is called privacy pass. I am not a huge fan of browser extensions but I installed it and it works a treat. You can read more here:
