FBI: "Rather than search...type the business’s URL into an internet browser’s address bar..." I'm not sure about this one. Typos easily happen, and it's the typo'd domain that scammers might own. Risky whatever way you go I suppose. For well known businesses I'd rather search and click on organic links than trust my own typing of a URL.
"Use an ad blocking extension". Third time's the charm. Great to see this advice coming from the FBI.
