What is Avast Cleanup?

Avast Cleanup is an optimization tool that supplements your Avast Antivirus protection, and is also available as a standalone application. Cleanup scans your system to identify unwanted files and programs that can be removed or disabled so that your computer runs in an optimal state.

How do I get Cleanup on my PC?

Cleanup is included in Avast 2016. Simply upgrade your current installation of Avast Antivirus. Scanning to see if your system needs a cleanup is free, but performing a system cleanup requires a paid activation code.

If you do not use Avast Antivirus, or simply prefer to use Avast Cleanup as a standalone application, you can download it from the Avast website.

If you have Avast Antivirus installed on your computer, we strongly recommend using Cleanup as an add-on in Avast.

How is Cleanup better than the old GrimeFighter program?

Avast Cleanup has the following enhancements and improvements:

  • Easy to remember system requirements: if your PC can run Avast Antivirus, it can run Cleanup.
  • System scan and clean happens within the Avast user interface. No reboot to Linux needed to clean files and settings.
  • New features include the Registry scan which removes obsolete files from uninstalled programs.
  • No more license hassles, just purchase and activate from within the Avast program and you are ready to optimize your PC.

Can I use my GrimeFighter license to upgrade to Cleanup?

Yes you can. Your license should convert automatically and remain valid for the same duration as the GrimeFighter license.

If you purchased GrimeFighter but did not activate it yet, you can activate Cleanup using your Avast Account. For details please read the following article:

Can I continue to use the old GrimeFighter?

Yes you can, but please note that if you update to Avast Antivirus 2016 you are automatically upgraded to Avast Cleanup and the GrimeFighter program will not be available on your system. If you prefer to use the older versions of Avast and GrimeFighter, you can keep the virus definitions updated to ensure your protection.

Is Cleanup available as a standalone application?

Cleanup is now available as a standalone application. You can download the standalone version of Avast Cleanup from the Avast website.

If you have Avast Antivirus installed on your PC, we strongly recommend using Cleanup as an add-on in Avast.
