Adblock Plus for Internet Explorer is quite easy to use. Just download and install it just like any other Windows program on your system. However, as IE won’t allow third party extensions by default, it will ask you to enable it on the next start. Just enable it and restart your browser. Adblock Plus icon will be displayed on the status bar. Click on it to configure it.
For your information, Adblock Plus for Internet Explorer is still in development stage, so you might come across some issues while using it. It can be downloaded free from developer’s web site here.
