I get redirected to different websites or see pop-ups on Google Chrome

I get redirected to different websites or see pop-ups on Google Chrome. Some pages are sponsored (casinos etc.) and some are very suspicious which I won't let fully load and open up.

I've tried to find a malware from my mac, but can't find any.

i've reseted the Google Chrome browser settings, but that isn't helping either.

I'm out of options! Can I get some help and advices please?
