I clicked on a link i HuffPost and was redirected to a page that wanted me to let some program "fix" my "screwed up" drive, etc. It wouldn't let me quit the page, etc. I then tried to type in words in the url of the browser, but they would not finish or give me the list of suggestions, for example: MacTech would not fill in http://fo rums.MacTech.c om/ ubbthreads, etc. [without the spaces smile]

So the solution for me was to run DNSChanger Removal Tool.app which I still have but don't remember where I got it.
