On the other Browser Cleanup is also a default part of all Avast antivirus solutions (Free Antivirus, Pro Antivirus, Internet Security and Premier).
Our new Software Cleanup feature gets rid of them once and for all. It also doesn’t require any installation, you can simply download and run it. To use Avast Browser Cleanup Tool you don’t need to have Avast antivirus installed, it’s an independent stand-alone application. It can even fix the hijacked default search settings or simply restart your browser to its original clean state. Bad stuff like annoying toolbars, useless extensions and add-ons.
Third-party toolbars are something that can appear in web browsers after you install some software.
