norton power eraser use 2 questions

Before I download the NPE I wanted to be clear on the following points. 

 

1.)      Does the tool remove infections or make corrections as it runs?  Or does it provide a log first and allow the user to decide what changes to permit?  

 

2.)     I think the NPE tool may have instructions embedded within the download; however, is there a helpme file link that I can read before downloading the tool?
