When I enter Google Chrome I get redirected to QSearch

This is the first time I'm writing here, but I've already informed myself and solved some problems I've had on my macbook with this forum, so I'm posting my problem here to try to get help. For some time now, whenever I enter Google chrome (the browser I have always used) the main page and the main search engine appears as *** and directs me to the QSearch page when before it always directed me to the google search engine. I have checked that the default browser remains google, I have removed all extensions and defaults where QSearch and near by me appear but nothing solves it. Has this happened to anyone else? If someone could help me solve this problem (it seems like a problem to me) I would really appreciate it. Many thanks
