Avast Browser Cleanup is a program that acts in the background to protect your browser from installing unsafe add-ins. These are the extensions that appear to be useful, but, in fact, can hijack your browser or steal your private information such as passwords, credit card numbers and so on.
Avast Browser Cleanup is really simple to use. You only need to install it, and the program will perform a complete cleanup of your default web browser. After that, the program will monitor its behavior in the background. This application has an extensive list of suspicious sites and add-ins, so when your browser downloads or attempts to install a dangerous one, the program will warn you so that you can decide if you want to install it or not. You can always change your default web browser. Each time you do so, the program will perform a cleanup of the new default browser to detect and delete bad add-ins. It also generates a log file for your reference. The program allows you to change the default interface's language (English) to any of more than 20 languages it features, such as Spanish, Polish, Chinese, and so on.
The application has a nice and clean interface with a few options, so it is very straightforward.
In general, this is a nice and useful application that you can use for free.
