Isolated issues like this - one search term in one browser with one search engine - may not seem significant. How many people have been affected by these short-lived but recurring hijacks that Microsoft is letting through to millions of people? It's inexcusable that these types of ads aren't vetted properly, especially when the majority of browsers automatically know these sites are unsafe. There's a pattern here, and it's a disturbing one. If you have to use Windows 10, don't use Bing for search.
