What Is Program Open?
Program Open is a browser hijacker that may end up on a Mac after a user installs a free or cracked app or opens a file downloaded from a questionable source. A browser hijacker is usually a browser extension/add-on; it can alter homepage, search engine and similar browser settings and stop users from changing those back. Program Open sets the search provider on Google Chrome to a fake search engine which redirects users’ search queries to Yahoo. You may follow this step-by-step guide to remove Program Open from your Mac and get rid of the search redirect caused by the hijacker.
