Sorting the safe from the scam seems a terrible way to spend an arvo playing roulette, but sure if she feels she must. Personally I have been very successful searching without those advertisements. You can hover over them as you go past, and their links are invariably complex enough to nope the hell out. I don't need that sort of risk in my life.

If she honestly wants to shop H&M (USian I'm guessing?) or David Jones or whatever, she should go to their website. Even the most humble local shops have websites these days, my local custom paper seller has, like most shopfronts, had its website long before the shopfront arrived in the world. And buying from the small and local is better for the environment, better for your home town, and more reliable.
