safari
I'm having two problems with Safari. First every time I use google as the search engine it automatically switches to a different one (bing, yahoo etc) to produce the results. I have google as the default search engine in preferences. Second when I quit Safari it automatically restarts there is nothing that I can do to quit it without it restarting automatically. I've tried to force quit, restart and shut down and restart and the same thing keeps happening. Any suggestions to my issues? I'm at the point that I think there is malware on the computer but I followed suggestion that tells you to restart because the OS automatically searched and removes malware on a restart.
