Clearing the main page of unwanted junk

My site is not live yet. Every time I log in, I get a dialog box that I can’t remove that demands that I sign up for Monsterinsitht. Tonight, I finally wasted the thirty minutes required to do that, including accepting MonsterInsight’s and Google demands that everything I’ve ever put in Gmail or my website is available to be read and used without my consent, or so it seems. When I got back to my Wordprss.org site, therer was yet another demand, this time for OptionInsight. I do not, under any circumstances, want to have any more such trash on my dashboard but I cannot find a way to get rid of it. Even if I click an X, it won’t go away. I wanted to do something tonight with Divi but this junk is in the way. How cam I make this junk go away and never darken my website again? It makes me furious. Thanks. Sorry, I don’t know what to call this situaiton and therefore, don’t know what to search for on the forums.
