Error Smart....

Is the program Error Smart legit? Rogue? If legit, is it worth a :crap? They have a kind of ambiguous big orange "Free Download" button here at MajorGeeks (see screen shot below) that links to this site: http://advancedpccleaner.com/?gid=1066977793&tid=1770225 and it's for downloading the Windows-fixer "Error Smart". Has anyone used this? Is it free to use? Is there a trial? What's the deal? There is nothing obvious at their home page as to whether the program is really free or if it's a trial, or if it will just do what many registry "fixers" do: it'll say "you have 42 bazillion problems in your registry and hard drive. The full version can fix these for you, The full version is 71 bazillion dollars...." Their web site is just vague. It only says 'Free Download' but Nero is a "free" download too, as are tons of programs. The download is free, but using the program is not.... any answers?
