Designed to stop irritating Internet ads, Pop Up Blocker performs poorly. The interface is easy enough to comprehend, featuring clearly labeled buttons for enabling blocking, adding sites to an allow list, and dealing with Flash ads.
Unfortunately, in our tests, the application exhibited a rather frustrating performance, as it only stopped a few of the simplest pop-ups we threw its way and left Flash ads intact, even when we used the most stringent blocking scheme. The feature that limits the number of windows your computer can simultaneously open would be a nice touch if it didn't keep you from opening windows yourself.
Since tons of similar programs are on the market, we suggest most folks track down a more effective solution.
