Frequently Asked Questions

AdFender is advanced software that filters various types of content from web pages and prevents certain information from going out to web servers. Filtered content saves you valuable time and bandwidth and enhances your online privacy.

AdFender is a local content-filtering HTTP proxy server. Typically, your web browser contacts web servers directly to retrieve specific web pages that you request. Sometimes, however, web browsers are configured to use an intermediary called a proxy server. A proxy server is a program that accepts requests from a web browser to retrieve a specific web page and then contacts the web server containing that web page. The proxy then passes all the data from the web server to the web browser. AdFender uses the name of the web page (URL) that a browser would request as the base of it's operational decisions. If AdFender determines that the request is for an advertisement, the request is blocked, otherwise it passes all data from the web server back to the web browser.

You can add a custom rule to exclude specific sites from filtering. Follow the steps below…
  • Open AdFender main console
  • Click “Filters” tab and click the radio button next to “Custom rules”
  • Click the “Add” button and enter the rule “@@||^$document” without the quotes. Replace with your site
  • Click the “Add” button on the dialog and click “OK” or “Apply” on the main console
  • Clear the browser cache and reload the page
There are different reasons why AdFender may not be able to block ads in certain situations. Please note some of the common reasons why this happens and follow the instructions below...

  • Make sure your browser is listed on the 'Applications' tab and is checked for filtering
  • Make sure you have filter lists enabled on the the 'Filters' tab
  • If the browser updated automatically (running with admin rights), restart the browser
  • You may have previously downloaded ads in your browser's cache. Clear the cache and reload the page
  • Verify your firewall settings to make sure AdFender is allowed to connect to the Internet
  • AdFender does not filter secure web pages (browser address bar starts with https://)

Once you have verified the above, close all browser instances and restart AdFender. Browse some sites and open the AdFender main console. If the counters under "Current Session" have non-zero values, then AdFender is working as intended. If not, you can manually configure your browser to use AdFender as the HTTP proxy. The host name or proxy address should be set to "" (your own computer) and the port should be set to 7070 (default). Please refer to your browser help manual on how to manually configure HTTP proxy settings.

No. AdFender runs as a HTTP proxy server on your local computer. It does not depend on our servers for browsing the Internet.
A personal firewall (e.g., Symantec, McAfee, Trend Micro, AVG, Avast, ZoneAlarm) is a security program that controls access to the Internet. The firewall may be a freestanding program, or it may be part of an Internet security package. After AdFender is installed or updated, your security software must be configured to allow AdFender to connect to the Internet. When your browser tries to connect to a web server, it is instead connected to the local AdFender program and AdFender connects to the web server on behalf of the browser. When the firewall notifies you that AdFender is trying to connect to the Internet or act as a server, you MUST allow access, for AdFender to work properly. If you deny access, you must manually reconfigure the security software to allow Internet access for AdFender. Please refer to your security software manual on how to allow an application to connect to the Internet.
To install, simply run the AdFender installation program, "Setup.exe". If you downloaded the "Setup.exe" program, find where it was saved to on your computer using Windows Explorer. Double click "Setup.exe" to start the installation.
To uninstall, go to the Windows Control Panel, then click "Uninstall a program" or click "Add/Remove Programs" Select 'AdFender', then choose Add/Remove or Uninstall to run the uninstall. The uninstallation process will delete AdFender from your computer. It is recommended that you close all your browsers, before uninstalling AdFender.
