I downloaded the Avast Grime Fighter for my mobile, but I've put a file I needed in the trash. How do I recover this from the trash bin?
The Grime Fighter application is now called Cleanup & Boost. From what I see, the application still provides the possibility of viewing the items marked for deletion. If you have deleted a file, tap on Trash and then you should have the possibility to restore it to its original place.
