Use the official website, avoid ads.
avoid ads by using an adblock, i have no idea how some people use the internet without one.
You should know that as google is improving their algorithms to detect and filter fake services, that is also how scammers are using different techniques to deceive people to click on those ads so the best in just to avoid clicking on them completely to avoid situations like this.
you should also know that google is doing jack shit to filter scam/phishing ads, just check on reddit and you will see the kind of scam ads that get shown on youtube and google all the time.
if google wanted, they could have fixed it a long long time ago, they don't because they earn money from it, so they just look the other way while pretending they care.
again people, use an adblock.
