Hello,
It appears that the default Bing search engine has been redirected to an unwanted browser extension. I recommend checking the following places where the search engine might have been installed or added to your web browser.
1
Copy and paste the link below into the Edge address bar, then press Enter.
edge://settings/privacy/services/search/searchEngines
Make sure you have selected 'Bing' as the default search engine and 'Bing.com' as the shortcut.
If you see any other address bar search engines in the lists, remove them.
2
Next, go to
edge://settings/privacy/services/search In the Search engine used in the address bar field, ensure Bing (Default) is selected.
3
edge://history/all
Clear your browsing History, cache, and Cookies.
Click CTRL + H to open the History page.
Select Clear browsing data, All time, and click ok.
4.
Check the browser's extensions.
edge://extensions/
If you see any unknown extensions installed, remove them from the list.
5
Reset Microsoft Edge.
edge://settings/reset
Select 'Restore settings to their default values'.
This will reset the startup page, search engine, and pinned tabs. The browser favorites and bookmarks will not be deleted.
