HOW TO BLOCK POP UPS / POP UNDERS

   A pop-up is a graphical user interface ( GUI ) display area, usually a small window, that suddenly appears ("pops up") in the foreground of the visual interface. Pop-ups can be initiated by a single or double mouse click or rollover (sometimes called a mouseover), and also possibly by voice command or can simply be timed to occur.
A variation on the pop-up window is the pop-under advertisement, which opens a new browser window hidden under the active window. Pop-unders do not interrupt the user immediately and are not seen until the covering window is closed, making it more difficult to determine which web site opened them.

Opera was the first major browser to incorporate tools to block pop-up ads; the Mozilla browser later improved on this by blocking only pop-ups generated as the page loads. In the early 2000s (decade), all major web browsers except Internet Explorer allowed the user to block unwanted pop-ups almost completely. In 2004, Microsoft released Windows XP SP2, which added pop-up blocking to Internet Explorer.
Most modern browsers come with pop-up blocking tools; third-party tools tend to include other features such as ad filtering.

How to Stop Internet Popups

 There are hundredsways to help stop, block, or prevent pop-up, pop-under, and other Internet intrusive and annoying advertising on the Internet. Below is a listing of some of the more popular and widely used programs we would recommend trying. 

1. Enabling Popup Blocking from Within Your Browser

   • • Enable popup blocking from Microsoft Internet Explorer. To navigate to the popup blocker, click Tools → Options → Privacy, and then check the "Block pop-ups" option. 

     • Enable popup blocking from Google Chrome. Google Chrome should automatically block popups as a default setting, but you can make sure that the setting is enabled by clicking the Chrome menu, then clicking Settings → Show advanced settings → Content settings, and then checking the "Do not allow any site to show pop-ups" option.

     • Enable popup blocking from Apple Safari. Open Safari, and then click Safari → Preferences → Security. Select the "Block pop-up windows” option.

     •  Enable popup blocking from Mozilla Firefox. Like many other browsers, popup blocking should come already enabled. If, for whatever reason it isn't, navigate to Firefox → Preferences → Content, and then press the "Block pop-up windows" option.

        

       
       

       2. Getting an Extension to Add to Your Browser

        

       For added security, get an extension for your browser. Extensions add to the functionality of browsers in specific ways, adding a new tool or strengthening an existing one. Most browsers support extensions. Here's how you get to your extensions page on the following browsers:
       • Firefox: go to Tools → Add-ons → Get Extensions.
       • Chrome: go to Tools → Extensions → Get more extensions.
       • Internet Explorer: go to Tools rarr; Manage add-ons
       • Apple Safari: go to Safari → Safari extensions
       
       
       Choose a popup blocker extension that suits you and your browser. There are several popup blocker extensions that improve the functionality of your browser's popup detection. Some examples of popular popup blocker extensions include:
     • Poper Blocker (Chrome extension)
     • Adblock Plus
     • Better Pop Up Blocker
     • Flashblock
     • NoScript
     
     
     
     

     3. Using Software to Block Popups

     
     Use popup blocker software if your browser doesn't block the necessary popups. Sometimes, for whatever reason, your browser's popup detection will fail and a few ads will get through. Most of the time, fixing this is simply a matter of turning on your browser's popup blocker option. Sometimes, however, for simple peace of mind or for heavy-duty security, you'll want to buy or download software to get the job done. 
     
      Research free versus paid popup blocker software. Although most good popup blocker software isn't free, there are a few good popup blockers that are fully-loaded yet don't cost a dime. If you're hawkish about internet security, or constantly bombarded with ads, you may want to consider paying for software. With paid software, you'll usually get:
     
     1. • Easy installation and ready usability
        • All the bells and whistles, with most centering on detecting and removing adware and spyware
        • Help and support, with good customer service
        • Added security features, aside from just the bells and whistles
        Decide which software is best for you. Each user and computer's individual needs should ultimately dictate which software they choose. Still, here are some popular software options that many people choose to use:
        • Free software:
          
          • AdFender
          • Smart Popup Blocker
          • Popup Free
          • Ad Arrest Popup Killer
        • Paid software:
          
          • Super Ad Blocker
          • Popup Ad Smasher
          • AdsGone Popup Killer
          • Popup Purger Pro
        Install the software and let it work for you. After installation, tinker with the settings to optimize the software for your individual needs. If you want to add exceptions to your software, do this now. Otherwise, try surfing onto a popup-prone website and see the magic in action.
