Hello
The Power Eraser is a very powerful tool created to remove dangerous malware and should be used by experienced malware removalists. There is a brief description about the tool above the download link. I don't know if the link provided is the most up to date one or not, as I am not an expert malware remover and therefore would not try to use it. I wouldn't just go ahead and try a tool like that since I am not an expert malware remover.
