My browsers (except Safari) have now been taken over by www.searchnu.com/406 , and I have been unable to remove it by uninstalling/reinstalling, or by using security software such as Norton Power Eraser. WOT seems to be the only system that recognizes it as a problem. Thank you.
Its basically a search engine, returns good search results but The search results looks like google's old search results. I am not sure that if they have hacked google or bought searching algorithm from google.
