Ignore means that the add-on will be disregarded and kept in the browser, no matter what its rating is. If you want to stop ignoring the add-on, just click Stop Ignoring and the Remove option will appear again. In some cases, an add-on can be restored even after you have removed it. The reason for this might be that the add-on is protected by a so-called toolbar protector.
A toolbar protector typically prevents Avast Browser Cleanup from reliably detecting and removing add-ons, resetting a search provider, or setting a homepage. In some cases the add-on can be removed but will be automatically restored later e. Avast Browser Cleanup tries to detect and remove toolbar protectors at start up.
However, some of these protectors are hard to identify and remove. Please report such cases through our support channels and provide the Avast Browser Cleanup log file. Unfortunately malware creators sometimes try to get access to your information by taking on a legitimate company or product name. This might lead to the strange situation that Avast Browser Cleanup rejects a seemingly safe add-on, because it is actually just a fake add-on posing as a legitimate one.
If a browser is threatened by a poorly rated add-on, its search and homepage are most likely hijacked too. This means Avast Browser Cleanup needs to reset these pages unless the search provider or homepage are on a known list of safe providers. Avast Browser Cleanup is unable to decide if a homepage is an intended one or if it is hijacked by the poorly rated toolbar. Therefore Avast Browser Cleanup offers a list of approved and Avast-tested new search providers combined with homepages to choose from during the removal process.
After the selection is made, the new search provider and homepage will be set. The current list of offered search providers is limited and depends on the customers location and country. If your preferred search provider or homepage is not on that offer list, you can easily change the browser settings once the browser is clean.
In general, Avast Browser Cleanup reports and recommends to remove all third party software which prevents Avast Browser Cleanup from reliably detecting and removing browser add-ons or search providers.
We call such software a Toolbar Protector. It does not matter if this software is installed by the installer of a poorly rated add-on or by the installer of a highly rated add-on. The result is the same: All add-ons are more or less sealed into the browser and can no longer be removed easily by the user or by Avast Browser Cleanup. Additionally, some Toolbar Protectors re-install their associated add-on even if the user manages to remove it.

A web browser , also known as an internet browser or simply a browser, is a software application that lets people access the World Wide Web. With a web browser, you can browse any website and easily navigate to other sites, similar to how you can browse stores at the mall, lingering in those you like before moving on to visit new ones.
Web access is as important as having a home address and telephone number. So just about every computer, tablet, and smartphone comes with internet connectivity and a web browser application. And with the largest library of extensions among the leading browsers, Chrome is also an extremely easy internet browser to modify and customize. Safari is the default web browser for all Apple devices: Macs, iPads, and iPhones.
In fact, Safari is the most popular mobile web browser in the US. Edge is built on the Chromium browser platform, which also underpins Chrome and other browsers as well. Once one of the most popular web browser applications in the US — and the successor of Netscape Navigator, one of the earliest commercially successful web browsers — Firefox has recently lost market share to Chrome and Safari.
But despite the drop in popularity, Firefox still boasts a small and loyal following while offering browser features similar to its more dominant competitors. While never the most popular browser, Opera has built a steady user base over the years.
This is due in part to the unique features the browser offers, such as a built-in proxy and ad blocker. All of the browsers listed above have their own private browsing modes, but only Avast Secure Browser makes browsing securely and privately its main attribute, not just an option or afterthought. Its extensive list of security and privacy features includes built-in protection against phishing, web tracking, and browser fingerprinting.
It also includes a built-in ad blocker and offers easy-to-set-up automated security alerts. Most of these features are enabled by default or can easily be turned on, making Avast Secure Browser the best solution for anyone looking to safeguard their privacy and security online.
