Safari won't open
Hi, while using Safari I got a prompt alerting me to a Flash Player update. Went thru the process, but was told I already had a more advanced version of it. I noticed that during the installing process that Safari quit. When I tried to reopen it it would start to open them quit. During first time a window opened for "advanced mac cleaner". I did a find for advanced mac cleaner and trashed it. But Safari will still not stay open. Any ideas how to fix this?
