I download the testdisk program but after the scan it doesn’t say it found any file and option doesn’t seem to recover the information. Please I need more detail help. Thanks.

I run the program. It recovered around 300 files the first hour, and then it didn’t make progress recovering more files. I stop it after running 20 hours aprox. because it indicated a estimated time of completion of around 7800 hours. 
So I still haven’t recover most of my files and I appreciate any help from anyone.
Thank you.

Scan the recovered files with MbAm and avast before using them.

Have you read what is my problem about? Avast make me lost all the files from my external disk. Around 400GB of personal data. Do you think I will use avast again? Is worst than virus. The most negligent or dangerous software I ever used.
Does anyone know how to ask directly to Avast to repair the damage they have caused?
