RootkitRevealer

RootkitRevealer is a proprietary freeware tool for rootkit detection on Microsoft Windows by Bryce Cogswell and Mark Russinovich. It runs on Windows XP and Windows Server 2003 (32-bit-versions only). Its output lists Windows Registry and file system API discrepancies that may indicate the presence of a rootkit. It is the same tool that triggered the Sony BMG copy protection rootkit scandal.
