New tool: Grime Fighter

I am using Avast Free Antivirus. Suddenly a new tool seems to be available:
Grime Fighter. Is this also free, or what is the cost?

Thank you! S I Jonsson, Sweden

Do not use it, more trouble than its worth.

I think it’s rare people actually get it working correctly.

MBAM and/or adwcleaner would be a better fit right now. Both are straight for general use.
