What is MacOSDefender?

MacOSDefender is potentially unwanted program for Mac that spoils browsing experience with constant redirects and advertisments. Once installed, it hijacks browser replacing default search engine/homepage/new tab with dubious search pages like http://www.alphashoppers.co/index.html. Moreover, it displays pop-up advertisments and causes redirects to shady pages preventing normal browser’s work. At first sight, there is nothing suspicious because new search page looks like other search engines like Google or Bing. Nevertheless, the quality of work of MacOSDefender leaves much to be desired. Actually, developers of this program make money only through advertising. The program displays altered search results which lead to sponsored and insecure websites containing malicious infections. Just one click is enough to get infected with the virus. Because of a high risk of infection, you are advised to remove MacOSDefender from Mac as soon as possible.
