How do I clean my browser?

You can clean your web browser by opening your browser settings, then 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 steps for clearing cookies depend on your browser. But generally, go into your settings to clear or disable cookies temporarily. Disabling cookies permanently can prevent many sites from loading correctly, so managing them is much easier with a dedicated browser cleaner. And if you’re looking for the best browser for privacy overall, get Avast Secure Browser and enjoy less clutter and more private browsing.

Will the Avast browser cleaner clear my browser history?

Yes! Avast Cleanup’s browser cleaner feature provides ongoing maintenance to keep your browser tidy 24/7.
