What is a PC optimizer?

A PC optimization app cleans your computer, improves disk access, and finds files taking up space and processes that may be slowing you down.

Avast‘s PC optimizer can help stop small issues from becoming big ones with Automatic Maintenance, Bloatware Removal, Disk Doctor, Browser Cleaner, and tons of additional built-in features. Free up gigabytes of space, get 30% faster speeds, and make your PC feel like new again with Avast Cleanup.

How do I clean and optimize my computer?

Once you download Avast Cleanup, cleaning up your PC is a breeze. All you have to do is open the app and click Speed up to unlock our powerful optimization features.

How do I optimize my PC for gaming?

Avast Cleanup’s Sleep Mode will help you harness the full power of your machine for gaming. Just open up Sleep Mode and put all resource-draining apps to sleep with one click.
