Why did a US flag icon suddenly appear on my Mac after a reboot?
I clicked on a link in a blog on my MAC Book and then a blue page came up and a voice saying that my computer was under attack and that I should call a certain number. I quickly forced shut down and when I rebooted. There is a US flag in the top corner of my nav bar. What doe sthat mean? Is someone spying into my Computer?
