Tried Google browser, Bing search engine, no problem.

Getting the same thing when I use Bing as a search engine. It's been working fine for a couple of weeks and now, any search using bing gets a red field with the words "Malicious Site Warning". I can Go Back Safely, or Ignore the warning. Choosing the latter lets me see the search results. I've tried this using Goggle and Yahoo, no warning (same sites). Opera 28. Going to try other browsers, maybe it's Bing, but I'm doubting it. Any feedback?
