RootkitRevealer is an advanced rootkit detection utility. It runs on Windows NT 4 and higher and its output lists Registry and file system API discrepancies that may indicate the presence of a user-mode or kernel-mode rootkit. RootkitRevealer successfully detects all persistent rootkits published at www.rootkit.com, including AFX, Vanquish and HackerDefender (note: RootkitRevealer is not intended to detect rootkits like Fu that don't attempt to hide their files or registry keys).

Version: RootkitRevealer 1.71
Super fast and detailed
Susceptible to being auto-killed by spy-ware and couldn't get it to run on x64 systems.
I'm going to go out on a limb here and say that most people below have no idea what this is for. It is simply a rootkit revealer, it does not scan for spyware or malware or give you any information beyond revealing items on your computer that you cannot see. It's up to someone who knows what they are doing to tell what has been found. This found a virus that eluded all scanners I have tried and it found it right away. I had to determine that it was the virus though, this doesn't claim to have that feature and it certainly does not have a feature like that. It does exactly what it is supposed to. A trojan did auto-kill this repeatedly and it won't open on win 7 ent x64. It did work on x86 though.
