Browse the internet in popup-free peace. PopUp Inspector's intelligent engine can block 100% of annoying pop-up and pop-under ads without interfering with your navigation. Unlike most pop-up killers, it works without human intervention; and there's no need for adding lists of blocked windows or allowed windows. PopUp Inspector blocks pop-ups before they can even start to download. This prevents pop-up and pop-under ads from stealing bandwidth or locking up your browser with multiple windows opening. In addition, PopUp Inspector will block websites or software installed on your machine from changing your home page settings. PopUp Inspector also reports and maintains a history of blocked windows, so you can see what companies are advertising via pop-ups and determine if you should stop doing business with them, or let them know how you feel. This handy application blocks Adware pop-ups, pop-ups generated by software running on your machine, messenger service pop-ups, Windows Messenger Alert pop-ups, and JavaScript error dialogs.
