Hostblock is an easy-to-use application that can help you block ads or unwanted host addresses to enjoy a smoother web browsing experience. It restricts access to the specified links within any program attempting to visit them, thanks to the fact that it relies on the Windows Hosts file.

The installation procedure is quick. However, you must have .NET Framework installed, since it was developed with the aid of this platform.

Once launched, Hostblock shows a large window that doesn't put emphasis on graphical elements, yet it's easy to navigate.

You can view the list with hosts it blocks by default, remove any entry with the click of a button, as well as add new hosts by just typing the URL.

The utility puts a basic search function at your disposal to help you browse a long list for a specific website. Settings can be saved to the Hosts file easily.

Moreover, you can export the list to file and later import it, even on another computer running this application. There's also an option implemented for wiping the entire list with one click, which can be later reloaded.

We haven't come across any unpleasant surprises in our tests as far as stability is concerned, since the software program didn't hang, crash or indicate errors. As we expected, it left a small footprint on system performance, since it needed a low amount of CPU and RAM to work properly. No recent updates have been made, though.

To sum it up, Hostblock facilitates a user-friendly interface and clear-cut options for personalizing your Internet surfing experience by eliminating access to any unwanted or ad-supported websites. It's geared toward all types of users, even those less experienced with such software.
