Never heard of it!
That means I wouldn't trust it as far as I could throw a Volkswagen.
Why not just download and use "Easy Cleaner 2", a program that's been written up many, many times here and on other forums as SAFE and EFFICIENT at cleaning up both a HD and a registry.
"Easy Cleaner 2" Can be downloaded from:
http://personal.inet.fi/business/toniarts/ecleane.htm
Just scroll down to "Download & Installation" and click on the first floppy disk symbol.
You don't have to go off into uncharted waters when you have easy access to something that's tried and true. And, it's FREE!
Good Luck,
Doc
