Smart PopUp Stopper Pro stops all annoying popups and popunders. You can allow popups by holding down Ctrl while clicking a link. You are optionally notified when popup ads are blocked by a flash of the tray icon and Custom-Speakers sound (or PC Beep). It optionally blocks banner ads for faster surfing. The available options for the blocked ads are: empty frame; '[AD]'- a frame containing the text '[AD]'; a frame containing the ALT text of the banner image; or custom image. It also gives you a chance to block the popup and banner ads of some commonly used freeware programs as Kazaa Media Desktop, Morpheus, Gator, iMesh, ICQ Lite and Pro, AOL Instant Messenger, MSN Messenger and Yahoo Messenger. You can also easily block GIF and Flash animations.
