I see that Castle Cops has approved this utility, but there's so little that appears in a Google search for the official site: http://rkunhooker1.narod.ru/ and there's very little information on the official site. I found this post in the Antirootkit.com blog: http://www.antirootkit.com/blog/200...r-author-to-release-new-undetectable-rootkit/ and it just leads to more questions. Has any other site studied this program yet? PC Magazine? Grc.com? If anyone can find detail reviews of the program by a software engineer, please post the link. From what I've read it has advantages over some of the other anti-rootkit programs because it supposedly removes the rootkit completely. I viewed this link to the Sysinternals forum that was posted in another thread: http://forum.sysinternals.com/forum_posts.asp?TID=11269&PN=1 and it appears that the author of Rootkit Unhooker is contributing to that thread. Has someone from Sysinternals analyzed the program and given a "thumbs up" to it? The author seems to feel that Gmer and the others are quite inferior to his program. It seems that if he's willing to discuss it on Sysinternals, it should be safe (answering my own question here). I'd like to see what others here feel about it. By the way, is it worth running Sysinternal's Rootkit Revealer: http://www.microsoft.com/technet/sysinternals/Utilities/RootkitRevealer.mspx and how is the rootkit program that Avira PE Premium has incorporated into its AV software?
