to manage your cache and cookies

If you’re looking for maximum efficiency from your browsing experience, you’ve found it with Avast Cleanup. Plus, streamline your whole computer with automatic maintenance and a dozen additional optimization features.


How do I clean my browser?

You can manually clean your browser by going into your settings and deleting your search history, removing cookies, and clearing the cache. However, as soon as you start browsing again, you’ll acquire new history entries, cookies, and cached files that need to be cleared again. The best long-term solution is to use a dedicated tool with automatic maintenance like Avast Cleanup.

How do you clear your cookies on a PC?

The exact steps will vary depending on which browser you use, but you’ll need to go into your settings to clear or disable cookies. Note that cookies build up every time you visit a website, but you also shouldn’t disable them entirely or many websites won’t work properly. That’s why managing cookies is much easier with a dedicated browser cleaner. And if you’re looking for a more secure browser to begin with, get Avast Secure Browser and enjoy less cluttered and more private browsing.

Will the Avast browser cleaner clear my browser history?

Of course! Avast Cleanup’s browser cleaner feature will provide ongoing maintenance to keep your browser tidy 24/7.
