chrome itself opens some kind of left site

chrome itself opens some kind of left site dota2game.org, if the browser is open, then it opens in a new contribution, if not, then the browser opens and transfers to this site. I also noticed that in the history of the browser above the list is the name of my pc and below it is this site, i.e. it is stored separately from the entire history. I tried all sorts of antiviruses, but I can't find anything. What is this anyway?
