Pop-up ads can be disruptive when using the Internet. In spite of this, advertisers continue to use them to make sure that their ads are seen. Your Web browser can block these ads. If you block pop-up advertisements through your Web browser, you will see only the pages that you want to when you browse the Internet.
Internet Explorer 8
Click "Tools," "Pop-up Blocker" and "Turn On Pop-up Blocker" to enable the pop-up blocker.
Click "Tools," "Pop-up Blocker" and "Pop-up Blocker Settings" to load the configuration screen for the pop-up blocker.
Click the drop-down menu next to "Blocking level," and click "High." This will cause Internet Explorer to block all browser pop-ups. Note that this may include pop-ups that you would prefer to see, such as those from web-based Instant Messengers, and that these sites will need to be entered as exceptions.
Click inside the box labeled "Address of Website to Allow," and type the name of a website that should allow pop-up ads. Click the "Add" button to add the website.
Click "Close" when you are finished. By default, Internet Explorer will display an information bar at the top of the window when a pop-up is blocked. This allows you to set up an exception for a pop-up window that you need to see.
Click "Tools," then click "Options."
Click the "Content" tab and place a check in the box labeled "Block pop-up windows."
Click the "Exceptions" button.
Click inside the box labeled "Address of Web Site," and type the name of a website that should be treated as an exception for the pop-up blocker. Click the "Allow" button, then click "Close."
Click "OK" when you are finished. When a pop-up is blocked, Firefox will display information notifying you, allowing you to set an exception if you need a pop-up window to be displayed.
The pop-up blocker in Google Chrome is enabled by default, and cannot be disabled by mistake. It is not possible to turn it off without using a command-line option or changing the shortcut used by Windows to launch the program.
Many major websites, such as Google, have no pop-up advertisements. If you are seeing multiple pop-up advertisements when you browse to websites that do not normally have them, your computer may be infected by malicious software. Use a spyware scanner such as Ad-Aware or Spybot Search & Destroy to scan your computer for malicious software.
