Why is Avast GrimeFighter a paid feature in Avast Antivirus 2015?

Avast GrimeFighter is a fully automated, standalone optimization tool for your computer that is meant to complement the services provided by Avast Antivirus 2015. Avast GrimeFighter provides an as-needed solution to clean and speed up your system by removing bloatware, trialware, adware, and other unwanted files so that your computer is running in its most optimal state. Avast GrimeFighter offers an array of benefits that are unique from other available optimization tools:

  1. Firstly, our “sedation” process allows Avast GrimeFighter to boot directly into a custom Linux environment to make changes to a "sleeping" system's Windows installation. This allows us to easily wipe away trialware, adware, and bloatware which can be difficult for other tools to reach when the Windows system is actually running.

  2. Secondly, Avast GrimeFighter’s strong focus on user experience not only makes it easy to use, but also enjoyable and entertaining. Even for non-experienced computer users, Avast GrimeFighter is a great tool to keep computers clean without spending hours optimizing their systems manually.

  3. Lastly, the Avast GrimeFighter engine is powerful in and of itself, but it is also greatly enhanced by cloud technology. Because Avast GrimeFighter’s intelligence is in the cloud, every user gets the benefit of real-time, community driven results from other users.

With so much to offer Avast GrimeFighter has been included in the release of Avast Antivirus 2015 as a paid add-on feature. For more information on Avast GrimeFighter, check out other FAQs.
