I am aware of those who say Apple Computers never are affected with being hit with a virus/scam etc, and until today I accepted that. However in the hopes of upgrading to EC soon I upgraded my Safari to the new 9ver. I am still using Mavericks. After opening my new download of Safari and browsing the web as I do on a daily basis, BOOM a screen shows up claiming to be from www.applesecurityalert.com telling me "Suspicious Activity Detected. Your Browser might have been hijacked and an anonymous activity has been detected...this is a major security issue........to fix it call Support for Apple immediately 1-866-782-9808." I could not turn off my iMac only by a force quite, when restarting the warning returned several times. So I called the FAKE helper and yes it was someone from India with an offer to fix my situation. I hung up called the real Apple Care Support who informed me this is happing more often these days. They cleaned up my computer caches and a few other things and I am back and running.......just wondering if the new Safari let this happen? That is all I upgraded for now. I am not looking for any confrontation about how secure our systems are, I just know that mine got hit. Maybe someone here can add to my puzzling situation.
