How to Block Popup Flash
Flash is an audio and video delivery method used by advertisers to add interactive elements to pop-up ads. Unwanted Flash pop-ups can bog down a computer's response time and create a distraction from the user's initial Internet activities. Flashblock, Flash and Pics Control and ClickToFlash are three free browser plug-ins that will block unwanted pop-up Flash.

Click the icon and then click to uncheck "Flash Animation," or click "Configure" and uncheck the "Display Flash Animation" box. Restart Internet Explorer for the changes to take effect.
Download and install the free ClickToFlash plugin for the Mac OS Safari browser.
