As far as I’m aware there is a free element to GrimeFighter - which doesn’t have the full features - this comes with all of the avast antivirus versions.
You can remove it or by doing a custom install not install it.
Windows Control Panel > Programs & Features > avast antivirus > Change - from the new window, in the Tools section, uncheck the option for GrimeFighter and that should remove it.
