Now for the browser question I recommend that you try to change Chrome's search engine;
Open Google Chrome and click on the three dots at the top right of the screen to access Settings;
Click on Search Engine in the left menu;;
Under Search engine used in the address bar, click on the drop-down menu on the right and change it to Google;
Now Bing shouldn't be your search engine anymore;
Hope I helped, see you soon!
