As I explained in the Windows 10 forum, I thwarted the W10 install by doing a System Restore. It did restore to the date I had specified, and of course that was only a couple of weeks ago with everything normal in my computer. So I don't understand why after SR I have no more search engines. None at all! When I type something into the search bar on top next to browser window, nothing happens. That's when I realized all search engines are gone.
How do I fix this and why would it do that?
I had by the way asked a question concerning a possible virus, here: http://www.bleepingcomputer.com/forums/t/586325/while-using-flash-player-chrome-froze-due-to-popup/
Could this possibly be related??
