Why Use This Popup Blocker Option? Price! In order to keep your business and loyalty, many Internet Service Providers will often offer free software to stop popup advertising. These products vary across the whole spectrum of quality, but the price is definitely right.
Pros: Free; these products are often promotional versions of high-quality paid products like Popup Killer or AdsGone.
Cons: Alas, there is no assurance on the quality of popup blocking you will get with these free products. For example: if your ISP popup blocker is an obscure locally-made medium-grade product, you may experience "false positives", where the product unwittingly blocks legitimate popups and login windows. The old adage can sometimes apply here: "you get what you pay for."
Where to Get These Popup Blockers: Check with you ISP help desk, or view your ISP home page for announcements on what popup blockers they offer.
