I have had a Samsung S6 about 1 month. Yesterday my chrome homepage got changed to some suspicious site (www dot psafe dot com -today dot org) so everytime I open browser it says I have a virus. The only option I am given is to install a "security update" this is suspicious don't want to do this. Chrome will allow you to change homepage but I can't get this far . . . the only option given is to install security updates (which I don't do - I close chrome). Under apps manager I can change the homepage for the default internet browser (purple icon, I assume written by Samsung) but don't see this change-able for chrome under apps manager).
