RootkitRevealer is an advanced root kit 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.




I searched everywhere and i could not find a good RootkitRevealer. So here is the one I use. A few things, U don't have to install anything just dbl click and it runs.
U can run it from a flash drive 2. Included is a chm file with all info about how it works, what a rootkit is,(if u don't know this might not help u very much)and more info.
