Well, it seems like a handy site, but it needs a LOT of work. First of all, the site is buggy and it took me five tries to get it to analyze a log. And when it did, the results were pretty inaccurate. Out of the 42 bad entries from the log I used, it recognized 3. And one of those was a legitimate entry. It also doesn't give any information about the HijackThis version, OS, anti-virus, or firewall. It's nice effort, but it's going to be a long time before it's ready.
Right now, you're better off with
HijackThis.de. Of course, you should never rely on a log analyzer because although they can be helpful, there are many characteristics they aren't able to look for. And they also don't pay attention to most file extensions. If an infection is changing your .exe files to .usr files, these sites won't be able to pick it up. Unless you already know how to read logs, you shouldn't use these sites. However, once you learn how to read logs, these can be useful in helping you double-check your work.
