A year and a half or so ago, I recall that there weren't many options available for rootkit scanning and detection on x64 flavors of Windows 7. In particular, Rootkit Revealer and GMER were non functional on x64 platforms.
Time has passed, and I'm wondering what options are out there that one can appeal to for rootkit detection on Windows 7 Professional x64? I know there's Sophos AntiRootkit, but beyond that I'm not terribly sure what's what. Which are functional on x64, which are preferred to use, etc?
Any help would be greatly appreciated. Thanks!
