Aobo Filter is a software application built specifically for helping you block adult websites based on user-defined keywords, as well as instant messaging utilities and web browsers.

The intuitive layout makes the blocking process seem nothing but a piece of cake, as most operations can be carried out with just a few clicks.

It runs on a stealth mode on your computer, so other users cannot detect its presence, and allows you to open the configuration panel using a hotkey, which can be reassigned.

The program offers you the possibility to create blacklists and whitelists by simply typing in the words or adding the URLs from the built-in web history viewer.

What’s more, you can edit or delete each entry added to the aforementioned lists, restrict access to all websites except for the ones in the whitelist, as well as make the tool automatically trigger the blocking process when it detects a user-defined number of keywords.

Not only does Aobo Filter ban certain websites, but it is also able to block web browsers (Firefox, Internet Explorer, Chrome, Opera), instant messaging utilities (Skype, Yahoo! Messenger, AIM, Google Talk), and tools installed on your system by simply dragging and dropping them into the main window.

One of the best features included in this utility is a smart system which keeps a log with the accessed webpages per user. Plus, you can refresh the current information with just one click, open each URL via your default web browser and view details about each link, such as title, date, and user.

Other notable features worth mentioning let you to check the list with the blocked websites, enable or disable the blocking mode for websites and applications, apply the settings to all users or only for the selected ones, as well as export the current settings to a file so you can upload them in the future.

Last but not least, the program features a master password for making sure other users cannot access or change its functions, or uninstall it.

During our testing we have noticed that Aobo Filter accomplishes a task pretty quickly and without errors. It doesn’t eat up a lot of CPU and memory, so the overall performance of the computer is not affected.

All in all, Aobo Filter combines an intuitive layout with a decent feature pack for delivering the best results when it comes to restricting access to different websites, web browsers, utilities, and instant messaging applications.
