The problem because of the ads.
This. Google is a terrible search engine for a number of reasons. The fact that they plaster ads at the top of every page would be annoying but not awful, if it weren't for the case that the ads are not vetted in any way and scam sites regularly appear there.
There are 3 pieces of user error here that all have to take place for this scam to work, and every one of them should be easy to avoid. First of all, you should never be using search engines to find links to Ledger, Trezor, exchanges, wallets, etc. Bookmark the correct link.
Secondly, if you are visiting any site, check the URL and make sure you have Punycode enabled. (In Firefox, go to
about:config in a new tab, accept the warning, search for
network.IDN_show_punycode and toggle the value to true.)
Thirdly, absolutely everyone should be using a good ad-blocker, probably uBlock Origin (
