I am getting popup ads on my iMac even though popups are blocked in safari preferences
I have recently started getting popup ads on my computer even though popups are blocked in my Safari preferences. They even appear on my homepage which is the Apple website. It seemed to start happening when I got the lastest version of Flash. I am not sure if that is the reason but it is very annoying. How can I prevent this.
iMac (27-inch Mid 2011), Mac OS X (10.7.5), My default browser is Safari 6.0.2
