Windows/fsavailux

Solved
Hello everyone,

I currently have a question regarding this program: fsacailux. When I plug in my external hard drive, a notification appears "security and maintenance - Check for errors on the drive". (sorry, I don't know how to hide the image).
When I click on it, the computer asks me to allow the program fsacaillux.
I can't find any information about it on the net, so I wanted to know if I could get some details.

Thank you in advance and have a great Easter weekend =D
